As low tier I can say that actually it isn't dead at all, but really, I think it won't last too much.
Once the "pve-mostly" guys will get their armor mounts they will probably stop pvp and so low tier matches will end,
splitting the queue I think can only make this die faster.

But also:
(in my experience most of newbies don't want to hear any advice anyway because they think they do nothing wrong)
This is the most disappointing thing in my opinion, untill you play the Palace of The Dead alone you can have fun to step on all the mine and frog trap you find,
but in a competitive and coperative content, this mind has to end, obviously people have to chill a little even when they lose.

Right now I'm experiencing too many 10 stack players in my ranked match, until they are in my server I /tell them to do do it and give them an explaination, but I would like to say it when needed not when it's too late.
