to be specific cone on a tank is a pita, because u r the one everything wants to chew on so that messes with targeting and how many u can hit

for dps imo,, cones r fine because they can have the comfortable side position where they can hit everything

HOWEVER i will say that on warrior the single most annoying part was having to move in out every goddamn GCD because of the different shapes, thus, it is much better to have shape consistency in ur aoe rotation (DRG is pretty unique, but every aoe is the same kind of line/block aoe)

SAM had likely the biggest inconsistency with their aoe shapes, i think it would have made more sense to just change the circle one to a cone, but at the end of the day a circle aoe is arguably far more convenient due to being able to aim freely and not requiring a target that can make aiming a pita/render ur ability to aoe effectively impossible
