When it comes to any sort of game with a crit-chance, I am there. If there's a skill, trait, perk, feat, or bonus that gives me more crit chance, or more crit damage, it's like a compulsion or something.
So, yeah... Borderlands 2. Looks like I'll definitely be taking the Assassin class and maxing out the Sniping tree. I can't help it - I'm just built that way.
If you want to find out how you're built, the new Borderlands 2 skill calculators are essential. They've just been posted over on the Gearbox forums, along with a mess of sub-forums so you can talk up your uber-nasty, super-killy, more wub-wub character builds.
Also... Boom, headshot, etc.
