Inferno vs. Haven

I tried using the suggested tactic in a duel against a medium-difficulty AI opponent. Haven, in my opinion, is very strong, especially with the Seraphs. Towards the end, when the AI starts frantically resurrecting them, it becomes quite difficult. Luck also seems to favor Haven, even though I've maxed out everything for Inferno. I think the game needs to be patched; there's a slight imbalance.
