Lost island HM, lol seriously Bioware?

This is where you are incorrect. These flashpoints are designed for based on what the last boss drops. Tier 1 flash points drop Columi, tier 2 flashpoints (LI) drop rakata.

So, I am a sage healer, and have run this several times with all different combinations of ranged/melee. I agree that moving the droid is difficult on all melee groups as interrupting incinerate becomes more difficult. So, I have quit doing that and just use the following strategy (I will give it for an all melee group, but I also use it with one ranged/one melee). I only use the 'drag-the-droid' around strategy with an all-melee group if the following approach fails more than 2-3 times.

The droid always stays in the center, so the tank can interrupt it. The ranged healer stands out from the melee, in the spot where you want the bubble to drop. The melee dps for about 8 seconds, then run to join the healer. Once the blue bubble of death is put down, the melee jump/run back to the droid, and the healer moves to the next bubble spot. The melee dps for 8 seconds, then join the healer again -- if any adds are around, dps those until bubble drops, then go back to droid in center. Keeping doing this until the droid is dead. It usually takes about 1.25 times around the room, dropping two bubbles on each side. At about 1.5 times around the room, you will hit the enrage timer.

This approach can fail if the melee can't judge when to run back to the healer and dps the droid too long, then a bubble can drop in the center. Generally, if the tank is smart, the tank can move the droid to avoid the one of these, but if more than one is dropped in the center it becomes difficult. The other problem is that if the melee dps is low, then you can run into the enrage timer since you lose dps running back to the healer. The advantages of this approach is that it is easy on the healer, so the healer can throw in some dps, and easy on interrupts, as the droid is not moving and the tank can catch all of the incinerate armors.

Good luck!

Ya if u guys are in full rakata and hitting enrages in there it is definetly a skill issue. We do it on are fresh 50 alts to get the columni gear and never have issues.

Pretty sure that's kind of redundant.

Also, I guess I shouldn't have done all those HM flashpoints when I had no Columi.

The gear is not relevant as some makes it sound. Most of those bosses have mechanics that makes them untankable if they are not known and executed.
You can be in full campaign gear, if incinerate is not interrupted right away, it will hurt again and again. It's the same on last boss with the bombs, if you don't dodge them, they are gonna hurt.

I'll do any time of the day Lost Island HM with a group in Tionese/Columi gear who knows the mechanic over a full group in Rakata/Campaign who doesn't.

Incinerate is a channeling spell, it has to be interrupted before the first 500ms otherwise it stacks up to 1 (possibly as well on dps).

The dome of electricity are not a problem if you control where they spawn, and having your group splitted up is the worst way to control where they are. Everyone needs to be moving with the tank, and have a dps focusing on interrupting and this will be a breath.

Last boss is similar, it has to be moved all the time, it will drop two waves of bombs for each kolto tanks, it has to be constantly moved before the 2 waves have been thrown. Once it's done, you can tank him where he stands up to the next kolto tanks. The tank has to be dodging his cone of attack as much as he can, as several stacks of bomb is a wiper.

This instance just requires your group to wipe a bit, adapt tactic, and make them working. The weekly gives BH comms so it has to be harder than the usual HMs, not even talking of the chest dropping here.

I've healed LI HM with my trooper in Tionese gear/level 50 epic mod gear. The tank was in Columi/tionese.

We cleared it in under an hour with two average DPS. (Average meaning 4 kolto tanks and 10 stacks of the phase 2 debuff).

This always bothered me about flashpoints and is one of the reasons our guild doesn't do them for quite a while now.
We are all for challenging content, but it HAS to be rewarding or it's just a waste of time.
If the flashpoint is indeed balanced around only the last boss drop, then please add something that makes sense to the other bosses, like daily commendations (which would be cool since I hate grinding dailys, doing flashpoints would be much better) that we can actually use for something, not total crap gear that you already have to have to complete the instance in the first place.

How is LI any different then the current tier 1 raids for fresh 50's? A fresh 50 with blues and greens will have some difficulty doing all the FPs but that's the point. Along the way they get geared out in Tionese very fast which makes the Tier 1 FP's even easier. After you complete a tier 1 FP you then are rewarded 1 Columi piece if you win the roll.

Columi dropping in LI from all the bosses is the same thing as Tionese dropping in tier 1 FPs.

Must all be smoking some serious drugs cause we 1 shot this each week and did it this week with 2 fresh 50's (1 dps and our tank maybe 14k and 19k health respectively)

Fights not hard you just have problems moving out of circles and predicting where lava shall come up.

If this fight is done correctly those health bars shall barely move downwards, i as a healer was able to spend half the fight attacking rather then spamming heals from poor damage dodging

(did anyone do this on the test server ? new loot tables to may be interesting to see whats changed)

Nope. To pick one of the "tougher" tier 1 FPs: directive 7 drops tionese-level and one columi piece. That FP is also a series of skill checks, but can be done in sub-tionese without autowiping from an enrage, even the big droid boss. You can walk into that and clear it in a situation where every player can benefit from every drop. I know that because I did it.

Walk into Lost Island without full T2 gear or equivalent on the DPS (or mostly T2 and an active stim) and you wipe on Savrak's enrage, which can't be outskilled. Sav-rak's got two mechanics, but he's not a skill-check. He's a straight up do-you-have-better-stats-than-the-drops-provide check.
