It's a big problem for a very long time. DKs can do none-stack AOE damage but most other DPS cannot. If you have so many DKs in the same map, you could almost NEVER use ANY SPELLS. The server latency is TOO HIGH!!
You could see SO MANY DK's debuffs on me. I cannot do anything but die in 10 seconds.
Please NERF DKs FOR THEIR AOE!!
