they actually kept nerfing the damage, i did used to enjoy running a full glass zerker fire staff build, sneak up on constested nodes and nuke it.
but for a long while every single patch came with nerfs to staff ele damage, and its just not worth running it anymore, it was already meme.
squishiest thing in the game and i can get more damage out of my warrior.
i'm still holding hope that next expansion will let us focus on one element, like a true RPG mage, none of this stance dancing style of play,
instead spec as a pyromancer and you get to hurl some serious nukes as a glass cannon.
