I had a chance to record a full GvG last night, and put together a video on it to show the effectiveness of a condi-spike group in that environment. Condi removal is thrown around the entire fight, but you still get a lot of damage in.
Build is 0/30/20/10/10, mainly because that is the build I am running right now for roaming as well, and I don’t like to swap up builds too often. The loss of burning and duration is of little effect in a GvG, and the staff traits help quite a bit in guardian heavy groups.
