Where the problem at?

DPS Checks cause players to adapt and push their classes hard while finding optimal ways to perform mechanics.

Most mechanics aren't that difficult, dummy dpsing isn't that difficult....combining the two is much more difficult.

Combining Tanking + DPSing - more difficult
Combining Healing + DPSing - more difficult.

Accusing Top players of using bots to reach that level of skill to make yourself feel better about sub-optimal skill levels is on a whole new level of low.
