the way aoe worked in tos was that aoe ratio dictates how many enemies can be hit with skills, and not the area itself, so you could have a very high aeo ratio but the area of effect of the skill itself is not that large, so you can’t hit more enemies even with a higher ratio. Also, if the skill has a really large aoe, managing and conducting mobs may not prove that rewarding, since the number of enemies you can hit is capped even if they are clearly inside the range of the skill. you can see enemies inside the animation, burning in hell’s flames, the world falling upon their heads and remaining untouched, because the flames of hell can only burn four enemies at a time…
i’d rather have all enemies inside my skill area to burn
