It's a valid reason to be frustrated, I won't argue that. But not having as good of gear and skill (maybe just your team and not necessarily you individually) is easily resolved by gaining that advantage yourself in the current environment. Gear gap will all but disappear tomorrow and completely disappear shortly thereafter.
No it will never completely disappear, the developers themselves said as much. There will always be stat differences between PvP tiers according to the Rob Hinkle interview. The main difference will be that everyone will have the exact same amount of expertise because there wont be an exp difference between PvP tiers. This means that everyone in a full set of PvP gear will have the same dmg/heal boost and the same dmg reduction.
There will be, however, differences on the main and secondary sets. War Hero and Elite War Hero sets will have more strength/willpower/aim/cunning/endurance/crit/surge/power/accuracy/alacrity/defense/shield/absorb than Recruit. The difference will not be massive, hopefully, but it will be noticeable. A person wearing full Elite War Hero will still do more damage and have more health than a person in full Recruit.
As for future PvP tiers, they are planning on a three-tier PvP gear progression. An unmoddable Recruit set, a set quickly obtained with nwz comms and a set that needs rwz comms and you can grind for. The overall stat difference between Recruit and the RWZ set is around 5% and the difference between the NWZ and RWZ set is around 3%. When a new PvP set is rolled out, the previous RWZ set becomes the new NWZ set and Recruit goes up a tier.
That way serious PvP'ers will always have a set to grind for but it will only provide a minimal advantage over the NWZ set. (If you have it, great, if not....well you still won't be gimped by your gear.)
