So today I was in WSG when I got a big lag spike. Not one to look a gift horse in the mouse, I grabbed the flag and ran down the tunnel, however, as soon as my connection caught up, somebody else had grabbed the flag as well.
We had two people with flags.
We got back to the base, and the other team had dropped the flag, so I capped it, and the other guy with a flag just sat in the spawn point. 30 seconds later when the final flag spawned, we instantly capped and won.
So Winlag + triple coordination = 2minute WSG games (provided all goes well).
