A lot of people claim it's MS due to its damage on SD's. However, I would go for ED for this one. Nowadays it isn't about the damage but about strategy and crowd control. Anybody can escape and tank nowadays, we have so many items to outheal the damage - the cakes, better mana potions, dishe etc.
It is the druid who controls the crowd, paralyses and enables the team to trap the victim, so that the sorcerers can take them down - if there are a lof of them, obviously.
