True, however wizards can get much better DCs. Also, there are divines other than FVS.
Agreed to your last statement. However, I'm confused. How are you are suggesting that AoE instakills should be addressed? Are you suggesting that Implosion should be changed or not? Are you suggesting that all AoEs should be treated the same? If so, I'll happily take a no cap limit and 30 second cooldown on Implosion.
