If these hardcore pvp features stay in through beta then DF is going to really require organization to win at. AE dmg spells kill friendlies and AE heals heal enemies as well. So the days of just spamming an AE blast or a healer spamming group heal are gonna be for the most part gone.

When the battle starts, and both groups haven't engaged yet you'll use the AE spells but once the two armies engaged eachother in hand to hand combat either you only get single target heals or you learn to train all heavily injured people to fall back and stand by a healer for an AE heal.
