i dont understand, im a tank dungeon hero for the tank mounts, i never ever ever had issues with W2W because my aoes were not a cone

aiming with ur character (where they stand) is not a hard thing to do, maybe u miss one mob every now and then while on the way to next pack, just tag it with a ranged attack and keep sprinting

a cone is really not ideal for hitting a large number of enemies as they pile around u

if anything, ask for a range increase on aoes in general, hell the caster type that needs a target and aoes around that target is such garbage, hardly ever hits everything and can even prevent you from aoeing because it is impossible to hit at least 3 targets
