There are 3 ways to lose (or win for that matter) in pvp
Sometimes its a combo of a couple or all 3. If you have pvp'd enough then you know when you are outplayed vs when you are outgeared. Im personally glad the T2 gear is gone for one reason: carries & win-trading. Its very easy for anyone to buy a carry to 2.2k, get the gear, and then keep on being bad...just less bad bc they push out bigger numbers. Its like dropping a crate of loaded M-16s into the chimp cage at the zoo, and opening the gates.
Skill + Experience + Gear should be what determines your success, and not a huge reliance on gear.
