Gunslinger Build (Lv. 10-200)

Well, it's a damage skill. It looks pretty damn powerful. Also, you cite some Rangers leaving Inferno at 16 but you don't recognize that nearly ALL Snipers leave Blizzard at 21. Cooling effect does low damage; even less than Blizzard. Its purpose is to freeze. That's why I'd leave it at 25.

Edit: Also, looking at that one vid where Fire Burner is actually displayed, it looks like it's doing more than Triple Fire on each target o_o

I'm an advocate for the burner build myself. (check out basil sometime)

Sadly, i've studied that video you're talking about and there's two conclusions i've come to.

1) We don't know his level, stat build, damage range, or skill build.
2) He's obviously 4th job, meaning amplification is available to him. By his freezing time, i think he has a decent level amp meaning his burner damage is a lot higher than it's base att.
