Crucible rep and marks should have to be earned in the crucible. Vanguard rep and marks are only earned in pve. The three factions are where things get messy, the vendors should either have a separate currency (which would be excessive) or accept both vanguard and crucible marks, while continuing to earn rep the way it is now. Selling mats should never have worked for crucible gear because it's not a crucible related activity. It's interesting that you consider 2 iron banners as pvp events, and queens wrath as the single pve event, but don't acknowledge how much pve stuff there is on a weekly basis already. Pvp doesn't have a daily with real rewards, a weekly, or a nightfall, nor do they have the raid (2 levels). Pve gets a new test weekly. As for weapon nerfs and buffs, they have to balance things out to keep everyone from falling into the same mold. This goes for pve and pvp.
