Oh no, because of your philosophy, a much deeper nerf to the Vistani is needed than nerfing the capstone (which by the way, yes, is an op capstone). Vistani gives a lot of good buffs, which together make it a tree as robust as the Inquisitive, and with the added bonus that its base weapons are not as useless as Xbows are without the help of the tree. And that's not to mention that everyone wants the haste boost, and according to your philosophy, everyone using something is OP. So nerf, nerf, nerf.
Nobody is using Vistan weapons? But what world do you play in? Kukri is the weapon of the moment, the vast majority of melee players are using Kukris, and they love them for the Vistan buffs and their excellent crit. So because of your philosophy... Kukris need a serious nerf too.
We could keep nerfing EDs, it's not fair that melee epic strikes are so good when casters' are so bad. And let's keep nerfing Fury's excellent healing. Why does such a robust dps tree give healing? Devs, according to these people that shouldn't be for other playstyles, so apply it to melee too. Nerf it!
Hey, I'm starting to like this whole nerf thing, especially since these are things that are really too powerful. I could go on listing a few more things that need nerfing.
But instead, I'm just going to point out that Inquisitive is the way it is because it makes a weapon that is 100% useless and no one used as a support weapon viable. Vistani was meant to be a support for weapons that were weaker than other melee weapons (though not as useless as xbows), but it's true that more builds are using it than daggers and krukris. I guess I have to agree with you, what devs have to do is make sure that no one else but those builds can use the tree. Fine, devs, do all this. At least then the whiny melee players on this forum will have something real to complain about. Just think, dev, that right now SWF dominates the ENTIRE melee landscape, that vistan is being OVERUSED, that kukris are already boring with so much abundance. People who complain about other playstyles having things overrepresented should admit that these nerfs are fair.
And when you're done with these nerfs, move on to ki bolt, which is completely stupid.
