Honestly, Who cares?
This is a pure PvE co-op game. People bringing more damage into your raid group can only ever be mutually beneficial, and eventually you will get more damage as you get geared as well. "Wow someone who is FAR more feared than me just out dpsed the hell out of me and carried the raid, how unfair!!!" Yeah that is SUPPOSED to happen??? Its not like you need the extra damage to begin with because they made the game so much more easier to steamroll. Stop pretending this is some awful change, it literally won't negatively effect you in the slightest. Also, getting the gear to begin with does take a degree of skill as well.
Besides...almost no one gonna have a weapon past +15 anyways.
To all those complaining about the +15 and higher - quit whining. I have a +10 and consistently outperform others with +13 and +14. I don't see many +15's anymore. Or, at least not outside of bank standing, like in actual raids.
