Hey,
I searched for this subject and all that came up was early start in AB, so if this is a repost i apologise.
Anyway, this weekend it was call to arms in Isle of Conquest, and some of us in BG found a bug where you could walk through the gate and capture bases before the game had started.
This is what you do:
Join Up >> Walk to the front gate >> Log out >> Log in, and while your on the loading screen spam, "W" and your 2 mous buttons to walk through the gate >> Mount up >> Win
Hope this helped,
~Shame
