Elementalist is mediocre in all for blobing.
If you want to play as support healer, Firebrand can do the same, and way better. Some might say, i play with them to provide some extra healing. We have med kit scrapper than shares the 50% incoming heal to allies around him as passive and gyros to barrier and cleanse conditions.
If you want to play as dps, Staff weaver is the option for you. You gotta get that Elements of Rage for that extra 10% damage and METEORSHOWERRRRRRRRRRRRRRR!, gets killed by retaliation xD.
Wait, what? You saying that Hammer Herald can do almost the same but with lower cd?
