I dont know how is this a problem for you if you're low geared. Dont just hit 80 and cry for being around the big boyz. The reality is, this server has been around for a long time which means, majority of players are full gear on 20 different alts. Either way, you can always do RDFs to get emblems and get furious gear quicker.
I managed to get 2k rating on a half blue items disc priest. (Tailoring PvP set) and from there onward, I do 10 games per week to get full wrath. I dont even bother farming BGs for offsets. Since I have max characters in my account, I do Wintergrasp weekly quests, buy honor with shards, send it to my newly 80. Plus, I can get shards from RDFs.
Anyways, from my experience, it will not take me 5 years to get full gear like everybody else, its roughly one month until I am almost BiS gear. So learn how to accept the fact that not everyone just DINGED 80. Accept that gear unbalance is normal for an old server. Find ways to get over it.
