Treek is broken, worthless, we paid REAL MONEY for her.

She's not worthless, certainly. In fact, I'd argue that her new value as weakest companion is actually a good thing. With most companions now you could AFK in the middle of a mob, get married, have 3 kids, cheat on your spouse, get divorced, and die broke and alone in a gutter, and as long as you have your companion set to heal, your character will never die.

Kind of nice to have a companion that requires you to use some conscious brain activity to play through the game.

As I've said before - probably in this very thread - Treek never was all that, anyway. Complaining about how you spent REAL MONEY on Treek, is about the same as complaining about spending "real money" on a fancy mount from the Cartel Market, that's basically no better than any other mount.
BW always said that CM items would not be "pay to play", and Treek is included in that. While many people liked certain aspects to Treek, about the only thing I found special about her was that she was the only healing companion that some classes could get early in the game. Beyond that, I never found her to be particularly better than any other healer companion.

So, to the OP, Treek is not broken and she was always worth no more than any other companion. Like most things in the CM, she was always just "cosmetic". You haven't "lost" anything - you never really had it.

Dude it was known by EVERYONE that treek was seriously OP. Before KOTFE, she was the easy mode companion.

Exactly, she is useless now.

You took the title as you read things, it didn't start with money, it started with a statement on her. In the post, you have to go to the 4th line to even hear anything about the real money part of it and 90% of it was about her lack of abilities. She's useless when it takes 50% longer to heal up using her than it does other companions. So again, the CORE issue was start first and foremost, the aggravating factor was put second, you just chose to read it as you chose to read it. If you had read the post, you would have known it had very little to do with money, but yeah, I know, most people are lazy and very few people actually read the post, let alone the pages to see what most of the discussion is about.

If she can be level 50, but be outskilled by a comp that is 15 or more levels below her, that is worthless. Unless you just like a little (cute to some)troll running around with you.

My point in bringing up the real money aspect was hoping to get her fixed sooner, rather than later, but when it comes down to it, the money aspect doesn't matter as much as the fact that she's been made useless, and far less fun than she used to be. If you played an assassin toon before she was changed, you would know how awesome she was, she could tank and heal meaning she could keep them out of your face so you could backstab them and she could also heal a bit leading to less boring downtime while running dailies etc. So yeah, again, if you played assassin you'd understand, we did lose something, we lost a comp that kept them out of our face and healed us up between fights, that's a pretty awesome thing to lose, not cosmetic and something that we DID have. Your mistake there.

We actually had to gear comps back then, and I had her in the same crystal gear that I had back then and she still wasn't OP, was it faster to get dailies done, yes. I've not heard anyone other than you complaining about her being OP back then(as we had to gear her), they were complaining about her being OP AFTER, read again AFTER KOTFE launch. Not sure where the confusion came in since it was clearly stated when exactly she was claimed to have been OP.

Yeah now your argument has no merit trying to say treek was never known to be OP. And YES I know you had to gear your comps back then, I had mine in all rakata gear when that actually meant something. This whole thread is about the fact that now your special little treek, is no longer as special as she used to be since all comps can tank or heal.

It seems your just butthurt about that fact, hence your whole argument that you paid real money for her, and want her as over the top powerful she was back then. And how dare BW make her in line with the other companions because of something as inconsequential as the fact it takes her a little longer to self heal.

At least her tank mode is underwhelming. Her tank and dps abilities have exactly the same names, 2 out of 5 abilities in tank mode are exactly the same as in dps mode, but with slightly reduced damage, and the other 3 abilities are the same as in dps mode with slightly reduced damage and some added mitigation and threat generation. While other companions have 2 taunts in tank mode (single & group), Treek has none. Treek in tank mode is more of a hardened/resilient dps than the actual tank services other companions offer.

The OP may indulge in a little hyperbole but they do have a point.
I'm not going to go into the cost of Treek, after all things depreciate even in a digital age.

Treek used to be the ONLY companion that could Tank and Heal at the same time, now she is the ONLY companion that can't.

I haven't checked out all the companions but they seem to have a generic list of abilities apart from Treek.
Let's have a look at TV-R8 in Tank stance;
Powered Charge does some damage, heals the comp for 25% of that damage and generates threat,
Threatening Focus gives the comp a shield and a taunt
Provoking Flare is another taunt.
Anti-personnel Detonator AoE that reduces incoming damage by 50%
Multi Grapple pulls in 3 targets generates high threat.

Treek on the other hand doesn't have any self heals, can't taunt (she only generates threat), can boost her armour by 20%, and has a 4sec stun (with a 2min cool down).

My influence 50 Treek wasn't performing that much better than the influence 1 TV-R8, pretty much only down to the fact she had far more health (about 30% more) and couldn't hold agro.

Treeks heal stance doesn't fare much better and seems to be very burst orientated with some of her core heal abilities. TV-R8 like most other healers has a far more consistent healing profile and can through a shield over the character as well.

I wouldn't go as far as to say Treek is useless after all you can use her to run gathering missions and crafting.
It's just a shame that in an effort to retain her unique abilities the Devs have actually made her one of the least attractive companions to quest with.
