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

Whether people acknowledge this as a problem I suppose depends on them

All I know is Treek's healing is significantly worse than every other companion I own (regardless how much higher influence she has)

Pre 4.0 Treek was a very effective healer compared to the other ones due to her strong abilities. Tank-wise she was a god for one reason: she doesn't break CC, something that was really missing on all the other companions.

Why would it matter whether "people acknowledge this as a problem" or not?

The people posting in this forum have no power to fix bugs.

Try this:

1. Start Parsec with Treek in heal stance.
2. Run some combat encounters.
3. Screenshot the result.
4. Repeat with another companion (and screenshot the result)
5. Provide details in the Bug Reports forum (with the screenshots).

Or, if you can't be bothered, simply continue to post how you "feel" that Treek is worse. Surely that will work ...

But don't mistake that for being "better". Prior to 4.0 the dedicated healers healed better than Treek and the dedicated tanks tanked better than her.

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.

Her value came from the uniqueness of being able to both at the same time, and as you said, not break CC.
But don't mistake that for being "better". Prior to 4.0 the dedicated healers healed better than Treek and the dedicated tanks tanked better than her.
