You can still do fairly decent even with barely any gear, in short rise above and just play better. Run more cc based comps and try to find partners who have bothered grinding the gear.
At the end of the day this is a mmo, blizzards goal is to keep you farming, a smart goal for next season would be to gradually grind the gear on all your characters.
If your looking to push ratings etc, i would suggest picking a good comp/class you enjoy and trying it, it probably wont be viable on better bgs but its still doable. Or, just wait a month 2/4 for next season to come around and start fresh.
His point wasn't that he is too shit to get 1900. His point is that his gear is way worse than any other player and it shouldn't be that difficult to get to the same gear level than other players since it is about competition and competition isn't fair if gear difference is this big.
