I'm barely having fun in ranked this season (rant)

I feel the need to vent a bit and also to ask your opinions on if those are legit concerns or I should just take a break.

1. If I ever choose support or fill as primary or secondary role, I get support. Not a single game on other role over 50 games on 2 accounts. I used to play support most of the time since the beginning of my League experience, but now I'm forced to choose particular roles to play anything else. And as a result, -1 potential support in the queue. It is less of a problem though.

2. Premades. First, there is little to no written communication on my team, maybe pings. I have to guess what we are going to do next, I get a bit lost or find myself doing my own things while the rest of my team groups somewhere all of a sudden. On the other side, I keep seeing unbelievably coordinated traps and flanks - it is disgusting for solo players. And the rule of big numbers doesn't work - i'm always solo while the enemy team can possibly be a 5-man premade. It's a big middle finger to all solo players.

3. I'll try to put all my balance-related rant here and to keep it short. Full AD comps that are running completely unpunished and don't seem to bother about armor. Also AD itemisation being superior to AP itemisation. As a result, if I go AP I have to pick something broken/op to be on par. The damage overall is too damn high. If in previous season being behind meant "oh well, we should play this teamfight perfectly while they can make a few mistakes due to being ahead", now it is "stay at at least 1 screen away from them or you'll get evaporated". The winning team can usually push all the way to nexus, only there can teams stall a game a bit.

As a result I feel like stop playing until a true solo queue comes out, after a few balance patches, as I just can't really enjoy games right now.
