SoD gets weekly tuning. You see any of that in Retail yet?
NO?
Whatever they do in SoD should stay in SoD. Dont take it as an inspiration. Simply because, classes are MUCH simpler than in retail.
Take tanks for example:
In SoD its enough to say: This class takes XX% less damage, and generates YY% more agro. DONE. Got a tank.
In retail its different. You need deff CDs of some kind. Shield block, Ironfur, Ignore Pain… Stuff that a DPS warrior (for example) for example does not have. You cant just get a warrior, slap a shield and say they receive 30% less damage and make it a tank. You need special abilities and a talent tree.
And the same way you cant just slap a 2-hander to a shaman and call that a DPS. You need more. And because you need more, its a full Rework right there.
And guess what? I know EXACTLY where this will end up: Same place Frost DKs and Fury Warriors are. One option will be much more OP than the otherone.
Have you seen any 1-handed fury warriors around lately? Why? Because if the WHOLE spec revolves around weapon damage and spamming abilities all the time you cant possibly make 1-handers better than 2-handers with only 1 talent. You need to rework the whole tree to make it work.
So you would get a half-baked 2-hander tree and a half-baked 1-hander tree. Better to ditch 1-handers and have 1 well built, well rounded 2-hander tree in the case of Fury.
