Sigh, played with an Ashe who went mid with Gangplank. Then when people started dying she called everyone noobs, and told everyone to go mid while she stood in base and didn't help with fights. Ugh.
I want to like this game but the solo queue normals, even at low levels, is so unwelcoming. Think I've only played one nice random Sejuani who didn't get mad and offered helpful tips during the game.
For me, I ended up playing a lot of Twisted Treeline 3v3 games while leveling to 30. You have less chance for afk/leavers, games are shorter, and you have more of an impact on the outcome of the game while learning it. Before I was 30, I prefered playing that mode unless I was with a group to play 5v5. Nowadays, I don't play 3v3 unless I'm playing a new/free champ as I find SR more enjoyable. Maybe just try it out to see if you like it.
