Look at rate of fire of cos sins and archers win.
dk got higher average damage(10k+) than sins, archer's(8k+) but
dk's att SLOW so it depends on what mobs you fighting lor. if mobs'
hp around 10k, dk can one hit ko most of the time. But if monster's
hp is lower than 10k, sins and archer win cos they have super long
range.
crusader's ave dam hard to calculate but basically is 5 hits they
lose, sixth hit they win.
