OP, dps is acrnym of damage per second and guess what, it is a function of time. Ur dps is dependent on fight length and varies based on how many capable players in the same group. If you have 4 dps with good skills it is easy to get 4k DPS, if u r the only good player among the 4 DPS< guess what u will never reach 4K, do not be so obsessed with DPS meter and instead you should use it as a tool to learn stuff
