Basically, the problem is threefold:
1) Some of the nerfs were never necessary.
2) Most of the other classes have since been buffed.
3) People understand how elementalists work now.
Anet really needs to go back and look at some of the nerfs they’ve given the elementalist and actually think up some buffs to go along with them.
Exactly how are elementalists compensated for having the lowest armor and lowest health in the game? Shouldn’t we have the highest base damage? Because we certainly don’t, dagger damage is AWFUL, especially autoattacks, and scepter damage is also terrible against anyone that doesn’t stand perfectly still.
