How do Guild War Points actually work?
The principle is simple: Higher difficulty missions earn more points for you and the Guild. Then there's the stage completion bonus that kicks in. But there seem to be some 'bumps' that activate and...I can't quite figure them out!
You can end on, say, 302 points as an individual tally, someone can spend their last few gas, maybe finish a stage...and all of a sudden, you've earned a 30 point 'bump' and...I don't know why!
It feels like you get a portion of points for having contributed to a stage or full 'islands' that ultimately gets completed, but I'm sure a bump has applied even after the Guild has already spent every drop of gas. Does anyone know the exact mechanism for these 'bumps', and how to earn them most efficiently?
