Uas..

I keep seeing talk about this "UAS" button. I'm sorry for being a newb, but can someone tell me what this is?

Unlock All Skill.

its from beta, hasnt been part of the game for a long time, and wont be in the future by all indications.

And this button did.. Just unlock all skills?

yes, it Unlocked All Skills for PvP only characters. So instead of having to unlock skills through playing through PvE or faction.. you just clicked the "UAS" button and use whatever skilsl you want.

Next time please use the Search feature as this has been discussed/mentioned/talked-about/etc many, many times in the past...

UAS is simply too short. Thank you, but I tried.

he is right UAS gets you the try again message

I stand corrected
I just tried and I just got the "try again" message as well.

My apologies for being so quick to jump on you then.... looks like there needs to be a sticky at the top of the page which explains a lot of common things.. like what UAS is, how runes work, etc... cuz they get asked a lot...
