I myself try not to cry hacks until I am 100% positive they are hacking. I suggest other people do the same and also learn class abilities so we can all be more informed and less ignorant.
Just a little suggestion, try putting in some keybinds to your abilities, notice you click every ability which is a giant time sink and very slow, you will be able to respond to things a lot faster
Yeah I really don't have a problem with taking on higher levels than me. Okay maybe not 10 vs. 49 but a skilled 20ish should be competitive with them. It really isn't a problem in my opinion
no lethality, it requires TA to use some of your abilities, which requires melee, which you dont want if you are that spec. Concealment is ok, but healing is the best for pvp currently
