hmmmm OK, I've never really built a full STR-based DPS Ranger, and my Kensai 2WF is still too low level, and awaiting the next Update for more level up, so I'll concede that I don't have only 100% full understanding of these questions from an end game perspective, although I have pointed out aready that I'm not just thinking of pure builds, and not just about higher levels.
... nevertheless, I can't find that I'm against this proposed change. Providing a good balance between the various combat styles is an absolute *imperative* if they are going to prepare this game for the Epic levels...
The biggest negative consequences will be that Rogues will generally speaking lose even more effectiveness, which is btw caused by a deep design problem in D&D, and that some people will feel that they have spent whole packets of Shroud ingredients on bad purchases.
Concerning Rogues, there absolutely HAS to be some effort by the Devs to ensure that they don't get left behind, starting here and now, with these 2WF changes.
I say Rogues, and not Clerics, FvS, Bard -- because these other classes have other powers that make up for loss of DPS, "merely" requiring a shift of focus or something ; Rogues have no such safety net.
Concerning ingredients expenditure, well it just sucks plain and simple, and I'm unhappy about it, even though I will not be personally affected by it (because my only toon that *will* get the 2WF nerf good and proper is also too thick to understand the concepts involved here, and will just carry on regardless).
