MapleSEA Episode 2 Aran Trailer

How are Arans overpowered? Their damage is divided between every mob they hit. It's really annoying to be honest. And that hole ''hit 12 monsters with normal attack'' doesn't seem to be true either cause with my first attack I could only hit 3, double attack seemed to hit 6, and triple swing finally seemed to hit 12(and let me tell you, the damage was like 700 700 500 300 200 100 miss miss miss miss).

While that helps things, it doesn't change the fact that they can handle mobs way better than they should while at the same time dealing enough damage to make them the strongest non-ranged class in the game on bosses...

Heroes at least suck on mobs, and the classes that are awesome on mobs suck at bosses. The classes that can do worthwhile damage in both situations are mediocre compared to the ones that excel in one area. Why then, can aran do both to the degree that they can?
