I know the feeling, its like starting a new account. Pre-30 matches are like this for the first few weeks of the season. I am not going to bother ranking for at least another week but i am excited for the new champ select as i feel it makes match making much better in a sense that there will be less people being toxic due to positions they are uncomfortable with. I am also disappointed in a way that they are accommodating players who only play one or two positions, fair enough if you have a favourite but making it so you get the lane you want every time will remove the need to learnt o play in other places and therefore understanding the game more.
I was reported yesterday for verbal abuse when i didn't type anything more than gj. I was support thresh and ended with a score of 1/2/26 and my carry ended with 16/3/8. My communications consisted of pinging, gj and gg. I am playing an alternative account which is still pre-30 at the moment. Reason for this is i wanted to play on another server to see the quality of their ranked leagues but the toxicity in pre 30 is crazy. Insta-locks and people just arguing over for the preferred position, picking it anyway and then you find that there are 3 people mid two top and just me on my lonesome bot. I am not great at filling in other roles but i am more than happy to do it, makes for a fresh change.
