I see some complaints (not many, mind you) about how Aeromancers are the new "n00b" PvP character, how you'll they can slap together the skills and just spam away.
So, what about making some of the Elementalist spells line-of-sight? Or, in other words, the spell follows a direct path, and if something's in the way (such as another enemy) it will get hit instead. Doing this will not only increase the amount of strategy needed for Ele Nukers, but also for defensive strategies, so you can "wall" your backline characters.
Plus, if enough spells were changed, it would also make Rangers somewhat more viable ranged damage dealers, as the choice would be power vs accuracy.
