To those in the know: is the number of weapon styles limited to two, or can i choose as many as I want, skill points allowing?
If you have enough skill points, you can spec into any weapon you choose. But make sure the weapons you spec into give you extra points for your role.
For example, I am an ice tank, so I need a lot of dominance and defsense. So I spec into certain weapon trees just to get the extra dominance/defense points so when I switch to tank, my dominance is almost 500 (currently 488) and my defense is 2131. The weapons I have specced into are Staff, Rifle and Brawling. As I get more skill points I will spec into other weapons that give extra dominance and defense.
So for controller, you need dominance and vitalization. For dps, you need power and might and also precision. For healer, you need restoration. Increasing things like critical healing and critical attack can help as well, so be sure to spend points on these when you can.
The styles themselves are limitless if you are specced into that weapon. So if you use a staff, you can collect as many styles as you want for the staff. I think my tank has about 7 different staff styles. You can change the style when you equip that particular weapon. But remember to be specced into it first. It's no good having a double handed hammer and you cannot use it cos you're not specced into it.
But if you get an epic weapon (that's the 97.1 dps ones) and it's either for your role or it's a dps only weapon, then I highly recommend speccing into that weapon.
Last night during our Khandaq raid, I picked up a tank rifle with 97.1 dps. I specced into it and that's how my defense is now 2131 and dominance is 488 and my health is a tasty 3011. Add that to the fact that after doing both Outer Caverns and Khandaq, I had enough marks of distinctions to buy 3rd Tier 2 piece which was the Superman helmet.
So there ya have it. hope that helps and then some lol
