Why is the Aran class so unpopular?

Arans probably have some of the worst flexibility of any class. Their attacks require a significantly longer amount of time to execute (i.e. Swing, Double Swing, Triple Swing, ...) so they're rather poor when it comes to OHKOing monsters.

They used to be popular because pre-Big Bang, they had retarded amounts of damage from Critical stacking.

Oh god I haven't played since pre-bang. >_< I really just want a fun job class that I can get kills on without being KSed so much. I was looking at Angelic Buster and I can see me getting my butt kicked by snails... Kaiser is a warrior class that uses combos. I love the combo system of Aran that's the main pull of why I picked it. Combos! FTW!
