At level 28 i can honestly say fighting the elite dude before you fight Jaesa is the only quest i have struggled with so far. Even the only time i have wiped a couple of times on one encounter, done all class quests alone....kind of ignored most of the quests in places just trying to do my class quest
Playing as Carnage spec...guess gear is my saving grace, always upgrading whenever i can.
So there i was faced with a 32 elite....Blew ALL the cooldowns, and just managed to down him....so then i speak to him again expecting to see some more role play....NO the bastid enrages and ***** my sorry ***:D So i just had to wait for my cooldowns to come active again, wiped a couple more times on it, it was some kind of leap that was screwing it up, quinn just couldnt keep up with the damage being split....almost gave up hope (ran out of medpacks and stims) went back to the fleet to buy medpacks/stims and thought bollocks ill have a couple more tries....
For some reason, when i engaged him again he seemed to hit like a girl, didnt do the jumpy thing but only seemed to channel spells, which before they could even do damage i interrupted. Phase 2 downed really easy, couldnt believe how much of a contrast it was before i went back to fleet....Dont think i even used a medpack!
Phase 3 was just as easy, waited for my cd's to come off again before talking to him again. But yeah, RNG is fun...just goes to show if at first you dont succeed keep trying, it appears he has lots of spells at his disposal and its just lucky dip whether you get the pain train (that kept wiping me) or the easy channeling spells.
So then the Jaesa fight, this was a walk in the park compared to her Jedi master, really no trouble at all.
So basically, its probably best to wait until 30+ before you try this, but then again if you like a challenge like i do....thats how it all turned out for me
TLDR; Last boss is a cvnt. Marauders aren't weak....
