AoE smiter is powerful but so is Ranger toucher. And instead of calling for nerf we can call counters.
Backfire = gg
Diversion = gg
Half the mesmer skills = gg
Desecrate/Defile Enchantments = gg
Or just attack the smiter--he can't do the chain on himself.
Please don't brutally kill that skill like Ether Renewal which is garbage now.
