As it stands, if there are multiple druids in the party, they will erase each other's Creeping Cold, Greater Creeping Cold and Creeping Doom when cast on the same mob. I believe these are the only dots in the game that behave this way. It is especially problematic for Creeping Cold and Greater Creeping Cold since they are backloaded spells and therefore if overwritten, the biggest damage is lost. Please change so that multiple druids aren't competing against each other for dotting.
It would also be nice if druids didn't overwrite their own dots, but at very least should not overwrite other druids' dots.
