Matchmaking is a mess right now. It is nothing new and very common opinion in the PvP community.
Sometimes you go in with three players new to PvP on the one side (you can see it when looking at their build/ilvl/gear/position on the leaderboard) and a team of only experienced players on the other side.
Or you have matches where one team has two healers and the other has zero. Or four healers on one team and one healer on the other. Healer numbers are somehow never even.
In matches where you have one team with experienced players and one team with only one new(-ish) player, the team with the new(-ish) player has to kick the one player that is trying to get into PvP and gain some match-experience. It frustrates the players trying to get into PvP and it frustrates the player trying to do competitive PvP. While one doesn't get to play PvP until he is skilles/geared enough, the other doesn't get even matches where his actions actually contribute to the win. Often the win is predetermined. If the competitive player has no kick left in the team, he knows he's going to loose, so most don't even bother playing and noone gets to play.
Another issue are people trying to piggy-back on PvP to get free stuff. We have matches where people queue with some alt that has Lion-Head-Weapons but 4k ilvl and 64k HP. Clearly these are trolls and/or people trying to get free stuff with as many alts as possible, without even thinking about winning a match. Slightly less frustrating are the PvE players doing that, but since most PvE-builds get squished in PvP, they don't have fun dying all the time and his team doesn't have fun because they have a disadvantage only because he is on their team.
Right now there is no place for competitive PvP and no place for casual PvP. There's only solo domination and it is no fun 50% of the time. Half the time you just stand around and wait until the match is over. And that is no fun at all.
There where many proposals how to fix this state of PvP:
separate queue for different ilvl
removing rewards for the lower ranks of the leaderboard
rewards for domination queue (and fixing the queue)
reducing the kick-cooldown
just to name a few.
It would be nice to know if this is on your agenda at all or if we have to get used to it permanently.
