The removal of conquest/arena points and rng gear ruined that aspect of rated pvp for me. I agree with OP that the people calling for solo queue are missing the point. The reason almost no one wants to queue these days is because pvp is truly awful - so solo queues wouldn't fix that problem. I can see Blizzard going that direction though - instead of focusing on fixing the actual problems (for which they are 100% to blame for) they apply a bandaid that masks the problem while pretending everything is cool.
(slightly offtopic) To reiterate: the reason pvp rng gear is bad while pve 'rng' drops are 100% okay is because pve isn't true rng as in, any mob can potentially drop any item. You can farm specific instances for a drop. Also you're not expected to have a full 40man (ahem, 25man) raid in BiS gear in order to be competitive for next tier's raids. In PvP the situation is different - if someone isn't fully geared (even if it's just .1% more hp - it's the principle that counts) it's simply not a fair competition. PvP is about equal chances and having individual skill and group synergy decide the outcome.
