Psykeeper facetank

Hey, I was wondering if it’s possible for me to switch from 1v1 psykeeper to AoE Facetank, I just hit level 90. I have an angel wand ready, and most of the level 90 set which seems that it’s made for AoE. I’m full int now, but I’m willing to restat to half int, half STA. I also have a level 80 FSRM if that helps, is this worth it, or should I just 1v1 to lvl 100 and unlock the well skill to HnR??
