Remove necrotic strike, mind numbing poison and curse of tongues then I will agree to 1.5 sec ring of frost.
O hay back to comparing classes. Take out all cast time debuffs, don't let spell haste go above 35% and entirely change necrotic strike to Offensive Power Word: Shield. Its overpowered as hell when it stacks and borderline useless when it doesn't.
Can we stop comparing classes now. Deep ring was OP and you know it.
