Yes and no.
No, mostly because it would feel like my characters have lost all their strength/progression etc.
Yes, because if everyone is back doing around 5k DPS Specs/Classes will be much closer together again meaning entire specs won't be sat out from raiding as often.
I.e. 2 Classes now one doing 120k dps another doing 110k dps in similar gear, 10k damage looks to be a big difference.
If in similar one class did 5.5k dps and the other class did 5.3k dps. The difference looks a lot less. of course it won't stop min/maxers, but it would reduce the amount of pseudo-elitists since with smaller numbers they probably would not get on the "HURR UR BAD DPS SPEC" bandwagon as much.
