It's unfortunately obvious at this point that they don't plan on making any changes before the engine upgrade 'comes out', all they're currently doing is hemorrhaging the players they have left by not making simple changes that surely wouldn't require much time or manpower to implement.
We're not asking for huge swathes of content or to fix every issue people have with the game (because yes, that's impossible) - it's simple things to make it playable now, stuff like anticheat, threat seg, and following through on reverting medspray (when did they bring this up again??).
Despite the rant I do wish Matt & his team the best of luck with their workload, but I do think neglecting the current game-state entirely was a questionable call, it's not as though revenue will come back in on a free to play game after its updated, you need a player base for that.
