I can't seem to complete a GR 70 with archon/FB, because I keep dying almost instantly when outside of archon.
Here's my setup : http://eu.battle.net/d3/en/profile/Taliesyn-2517/hero/77846944
As far as survival go, I try to teleport into large packs and spam frost nova to proc APD while channeling arcane torrent/flame ward.
Is my gear too lacking, or is it a gameplay issue?
As a side note, I sometimes have the feeling that some mobs are avoiding my damage : I've been standing right next to mobs with 2 overlapping archon stacks, and the wave of force didn't do noticeable damage.
