The other day my GC came in 1st and I got 600 PvP EXP and 900 Wolf Marks. That was the most i've ever gotten from a single match and I didn't really do much besides stand at Temple and repel the odd attack(wasn't very many).

Just now my GC came in 1st again and I was busting my ass off trying to hold Manor from almost non-stop assault and only got 400 PvP EXp and 600 Wolf Marks.

I've also noticed there are varying rewards amounts between 3rd places 200/300 reward and 1sts 400/600 in intervals of 5.

So how is the reward calculated besides who comes 1st, 2nd, and 3rd?
