what are the best skills to shutdown the Mesmer Titan in Titan's Source?

i got to these guys a couple of times now, with a couple of different parties

the Mesmer Titan always casts Panic and Guilt and whatever else he uses and it drains my mana down to zero instantly. apparently it does this to my other party members too. we all die very shortly after that

so i'm asking: how do i stop this Mesmer Titan? and his two other Titan buddies?

i'm looking for a very detailed layout - what skills to be brought and what class types to be brought - on how to make it so they don't own my whole party in 20 seconds flat

btw i play a Warrior, so we gotta have at least one Warrior in this party for the sake of this layout. all other slots are flexible.

please use as many details as possible when providing answers.

thx

Spread out a bit, have Hex Breaker on the guy who's going to take the hexes, and just generally don't clutter together too much. Having mesmer skills to counter it helps a lot too... If you've got a good mesmer, have him try to diversion the boss, while other players chain-interrupt him (choking gas, savage shot, etcetc). Also have a monk with hex removal skills.

Hex breaker will pretty much own him tho, just need to have one character to take the brunt of most of the hexes. Arcane conundrum would also help interrupting him. The rest of the deal is just straight out damage to take him down as fast as possible.

thx for the tips

i switched my secondary to W/Me now with 12 points in Domination and Hex Breaker on me

i got another question. after we clear out the tar pit, should we just rush the Mesmer Boss right away, while the Charr who are camping with the boss are still alive? or should we ignore the Mesmer Boss and try to kill those Charr first?

no one has any answers to this?
