My personal opinion (and what I believe Bungie is going to move towards) is using impact to govern the damage value in pvp and attack power in pve. Furthermore, I think a better solution would be to cap attack power to a specific value for all weapons in pvp (let's say 300), which would allow their pve attack power to be whatever it needs to be (say 300+) to make it relevant for its content. Then they can individual assign attack powers to weapons for pve balance knowing that a baseline in pvp will still be preserved. I'm also VERY tempted to say that weapon perks should be turned off in regular cruc and activated for Iron Banner. I realize that that is a very contentious idea and I'm not sure it's even a good one, but it's worth thinking about it.
