Personally I worry about an oversimplification of the class. I get that the devs have their own vision for the game and we often just have to roll with it or not. The roller coaster of tweaking that is probably going to happen is not something I look forward to. It may all end up for the best but I cannot say I am hopeful based on the other DoT revamps. I doubt the necro DoT revamp is going to amount to much in alleviating the debuff slot issue. I get the debuff slot limit is essentially an artificial cap on DPS as is the 54 person raid. You have a cap on the resources you are allowed to throw into an event that requires coordinating a large group. Optimizing that is another part of the game. If the raid team does not make better choices about which spells have priority, they pay a cost for it just like they would for not bringing a balance of classes. Personal DPS usually has to take a back seat to the overall raid DPS.
