Back in the day, this happened all the time: at the beginning of wintergrasp, on defense, we have an attacker atop one of our towers, nuking our guns from above. However, I thought that was fixed and I have not seen it for a while. Well, that happened last night. Exploit or working as intended?
I thought I read was that even if we flew into WG during the battle, we would port to a rally point (when we accept the invite?). I really don't think that is happening (for example, we were fighting in the fortress courtyard pre-battle and we simply continued fighting, right there, as it started; thus starting with some enemies within our fortress).
