Guild Wars 2

First, the questions:
*How are badge of honor drops determined? Is it just like in PvE and based on how much damage you do to the enemy, or what?
*I get that the Repel event is there to lock down WP so that attacking a place with one is actually feasible, but is it supposed to be capable of abuse as it seems like I’ve seen it, with people just attacking enough to activate it and then running off and repeating it to keep the WP from ever being used?

Concerns:
*AoE, and especially the cata attaking through gate is pretty BS. If people really want to do that, then ANet should turn on friendly-fire, they want to shoot catapult shots at their own gate or other abilities, they should take the damage for it as well.
*Siege inside a fort is fine. Siege on top of roofs inside said fort . . . no. Siege should require at least a semi-flat surface. None of this putting it on top of the supply roofing.
