I hope in GW2 they separate PvE and PvP skills... same functionality, but different values in PvE and PvP... that would sort things out (almost) once and for all. Who knows? It might actually happen.
And while the vast majority of nerfs make no difference to PvE, certain classes are getting less and less useful in PvE... a few select nerfs to skills abused in PvP could strike a massive blow to Rits, Paragons and Sins. And certain classes (I give the example of eles and the recent SF buff) are just getting better and better in PvE. (Here I talk about HM. I fail to see how any class will ever find the vast majority of NM PvE hard)
And I wont deny that PvE nerfs/buffs/additions haven't hurt PvP. Its a two way thing. But that just furthers my point that they should be separated.
Oh, and to those who say, "just use consumables", not all of the player-base can afford a powerstone + consumables for every area. And those of us that can... well, PvE is always about bettering your character. For example, most of my money goes towards armor sets, minis and (destroyer) weapons atm. And most of that money is from vanquishing. And if that money is spent on powerstones, I have nothing. I may as well say, "PvP is easy because you can get all the skills quickly, and make armor sets at the click of a button". I don't play PvP at all (except the occasional RA of AB), so I don't claim to know much of how PvE effects PvP, or the intricacies. I wont lecture you on something I know very little about. But I ask you to give me the same privilege.
And reading more of the posts, I feel it is necessary to fortify my rit/sin/para position. Paragons... well, yeah. You can contruct a very good support build with them. But PvE players often like a variation in builds. I will generally have my own made up "flavor of the month" build on my ranger. At the moment its a glass arrows hybrid. I've gotten bored with it at the moment, so I'm experimenting with thumping builds, to see if I can find a workable one for PvE. But I would get incredibly bored if I could only be support, as the paragon is rapidly becoming. Yeah, I'd enjoy it for a month or two. But it would get dull.
Rits, yeah, they have still got a fair bit of firepower. But spirits aren't nearly as versatile as they used to be. Well, I tell a lie. In certain areas they aren't as versatile. And as Anet has announced a plan to nerf it further.... well, I dread the consequences. The damaging skills, still good. But if they have a few nerfs on a few skills, they could destroy that method. And restoration will likely always be good in PvE. But I refer you to my paragon point. Rits aren't nerfed into the ground YET, but they are teetering on the edge.
Sins... well, sins in PvE are VERY hard to play at the moment. The sin in PvP was build around jumping in, dealing quick damage, then jumping out. This does NOT work in PvE, where constant pressure is needed. And in HM, the low armor of the sin does not make them good for staying in Melee. Infinite shadow form worked for a time, but then that was nerfed. So assassins, while good damage dealers, need the monks focus, something not given out easily in HMPvE, to succeed.
Finally, if he nerfs splinter, he will be nerfing the one of the few reamining ranger "AoE" pressure builds for PvE, and likely ranger involvement in elite missions. Again. Please do not do this.
