if your pure 2h, better spend it more on 2h, don't think there's a cap, only your lvl decides that and after 31 it pretty much gets uber hard to level anyway
Yeah. As far as I know, there is no WPF cap. But it gets extremely annoying getting like 120 WPF points per Weapon master, then realizing that those points will get you about 12 levels. That is, when you reach about 150 WPF in a skill, as you have.
After the new patch, chadz has made characters more susceptible to have split proficiencies. Since there's pretty much a level cap at 31, there is only a set amount of agility possible to get without ruining your character by not being able to use any weapon. Therefore, there is also a set amount of proficiency you can get into one skill. There is no room for getting more max WPF, so it's sometimes best to have 2 skills. So, I guess that would technically be a cap, but who's noticing?
