Since I started playing my warlock I've always been Affliction at heart. After 5.2 changes, I decided to join the bandwagon of Destruction and have found myself enjoying it nearly as much. I know that currently Destruction has the highest sim'd damage output of the specs until ilvl 522 at which point Affliction pulls ahead. My question is one of gear interchangeability. I would prefer to keep only 1 PvE gear set for raiding that can switch between Affliction and Destruction with minimal change in gems (reforging is much easier to deal with than having to swap gems all the time) as that allows my raid group to maximize the number of Haunted Souls acquired for crafting better gear for the group and also doesn't require me to constantly farm/buy new gems. I've noticed a few high-end destruction warlocks (talented GoSup) gemming nearly full mastery instead of the standard crit/haste>mastery. Would this gear set-up be severely detrimental to my overall dmg output? If so, should I look into trying to build 2 PvE gear sets? I'm only ilvl 500 at the moment.
