Re: Ability discussion: butter barrage, bigger better butter, and butter beacon.
I generally use bigger, better butter in GW2, but butter barrage is fine as well. I actually like butter beacon but part of that is I like the changes to spotting in BfN and both GW2 butter attacks have the issue where they hit some terrain feature and do nothing to the zombies as they explode harmlessly far above the battle, this is also at least partially why almost every building in GW2 has an open top or very high ceiling; so the butter attacks can be used almost anywhere, but the issue of outcroppings, overhangs, and other parts of the map blocking the attacks persists as it drops from the plane above.
That being said, beacon could use a buff. Have it last longer, give a bigger damage bonus, or other things to make it more effective and useful.
