Guild Wars 2

A huge chunk of the cast times are completely unnecessary, and they only add to the already long delays between the keypress and the action. That's not the only thing though. There's lag between when you press the key, and the cast bar even begins to go off. More than I'm used to.

See that I still don't see. I tried it on my own several times, and the second I press the number key the cast bar appears.

Also, the left to right strafe is very slow, and swiftness does not make you strafe faster.

This I agree with completely. Since strafing counts as an action I believe it gets put with Quickness for the boost instead of Swiftness. The problem is if you're using Quickness for dodging, you've completely wasted Quickness because it rarely lasts more than 4-5 seconds. I agree that Swiftness should include dodging. Maybe it used to be that way and people complained that it threw off their timing? But, dodging isn't effected by Cripple or Chill either, which makes no sense.

Greatsword and rifle. Working out pretty good so far.
I've got the signet healer, in my heal slot. I figure that the passive in combat health regen is going to be useful if i'm 1v1ing. Gives me some health gain without having to stop attacking.

Healing Signet is pretty insanely broken. The only issue with it is that if you actually need a quick heal you're screwed, because using it is extremely detrimental to your healing. It only heals like 1,000 at level 80, which is worthless. Look into getting the 15 point Toughness trait that gives regeneration based on your Adrenaline level too. Those combined make for some pretty bullshit Regen (For everyone else, not you).

I personally only use Rifle or Longbow if I NEED long range. Otherwise I stick with two melee weapons in my bar. Long Range on Warrior is really pretty crappy. It's mostly there, I think, just to give you long range possibilities. My DPS gets cut in more than half when I go from Greatsword, Dual Axes, or Hammer to Rifle. I switch up Dual Axes and Hammer myself, so usually I'm Greatsword and either Hammer or Dual Axes.

What level are you?
