I guess I was hoping arena would be a battle of who has enough mana, and hoping that the massive number of revitalize proccing would mean unlimited mana.

However, if I can get insta gibbed on even one of the trees then I'm pretty screwed. The only way for me to win would either be a stalemate (which I would win since 5 others would have to continue in the battle versus just me, and I'm probably laughing the whole time) or a slow war where their healers eventually run out of mana. The problem is I'm not even sure I could do enough damage to outpace another healers mana regen.
