Has anybody brought an AST to Alex Savage?

I'm extremely curious on this job's performance in that.

There's a 30 second period where healing is very intensive in A1 (Raid AoE everybody 50% life, followed immediately with T13's Earthshaker-ish attack, followed immediately with stupid strong Tank Buster on both tanks, and during all this time, there's adds poking at your 4 DPS for 1~2k per auto attack.), and I'm very very curious whether an AST has the tools to weather this storm or not.

P/S : The above shit storm repeats itself every 90 seconds.
