[BUG]+damage modifier bug
After a few tests, it seems that in order to fully take advantage of modifiers such as "+x One-Handed Edged Damage", you must equip the items with the bonuses AFTER you load the zone. You can do some testing of your own, but I was noticing that my weapons were at ~277 dps each after zoning with all my gear on, but if i zoned with my gear off, then equipped it after zoning, they were at ~366 dps.
Further, it's very likely that this isn't the only stat that is bugged--it's just the easiest(and most obvious) to test. I'd suggest that for raiding, pvp, or really anything you want the best performance out of your character and gear, that you zone into your instance completely naked, then re-equip your gear once you're zoned.
