Magister's Terrace

I haven't been able to complete this place on normal yet :( The first time I tried, I killed Delrissa with extreme ease by dropping 4x fire elementals, nuking the shammy down before stun wore off on Delrissa, then killing her. I barely took any damage as my fire elems caused confusion, and with an earth shock rotation, she was unable to heal herself. Alas, just as I had Kael at 40-something percent, the server lagged out and reset.

This weekend, I've been trying it again and cannot kill Delrissa. The warrior add (which I didn't get last time) will intercept me, aoe fear (even with 4 very carefully staggered tremor totems, it causes me to run all over the room). The intercept prevents me from getting the initial stun on Delrissa, so I can't nuke down the shammy. In the meantime, I can't heal very effectively thanks to the mortal strike debuff.

Do I just need to reset the zone until I don't get the warrior? Does anyone have any other tips/suggestions for a pally + 4x shammy team?

Edit: corrected 'grounding' to 'tremor'

If you have enough DPS burst down the warrior immediately (I've seen it done on some pvp geared shammy teams) and this should help a lot. If you don't have enough burst to one shot him perhaps you should spread out the tremor totems to ensure that they pulse on your guys before they get out of range (then FF the war down).
