There is way to much aoe after hot, and most of it is more powerful than singe target skills! This is a terrible design and makes for unfun fights. Things like dragon hunter traps, tempast overloads, scarper hammer 5, chronomancer wells, ect.
All of thees (and other skills) cover a point and do not require a target or anything, all it takes is for the caster to be on the point and facerole his keayboard. It is not a fun play style and it is not fun to fight against.
Ranger had a trait that made their spirits follow them that was removed not because it was uber strong, but because it was annoying to fight against that build. Well it is the same scenario here except it is not one class or a trait but aoe in general that is, not necessarily op, but kittening annoying to fight.
If the the fun/frustration argument could be used to remove the trait, then the same reasoning can be used to change/remove (not all of them) the stupid aoe skills in to something less facerole and more fun to fight.
