It is still not optimized so it's stability is a crapshoot based on your hardware and drivers.

I've never had it crash on me but I know people who cant play because of all the crashes.

The frame drop issue is server side. The longer you play the more frames you lose because of the way the server tracks things. That is "supposed" to be fixed in 3.0 in the next few months. But we will have to wait and see.
