Tbh, All of my friends and I who are primarily pvp players all have the same opinion on this.
PvP isnt about the gear, its about the PvP. You simply adapt to make the most of your class when changes are made.
Its kinda obvious that if you're a new 50 and un-geared that you aren't going to fare well against geared pvpers who have put time in on that character, but that doesn't mean you are useless forever, the gearing up in TOR is extreamly fast for pvp, and you can even do it without any pvp at all if you're willing to wait a while just doing the ilum dailys/weeklys in the morning when its dead.
People need to stop complaining, if you find yourself not viable in pvp as a new 50, bare with it, have fun instead of QQing and you'll be beating sticks with the best of them in a week or 2.
I can't beleive the sheer amount of crying and moaning on the forums about it all, there is none of this Ilum fight clubbing and stuff on my server (Frostclaw), the community is fair and friendly on both sides and ive seen no griefing at all. People should consider re-rolling on other servers if their ones are full of lame ppl wanting insta everything without working for it.
