I don't get this mentality...
Not to say it's wrong, not at all! I assume most people think this way, I guess just personally if I have friends online I'll almost always play with them. If they suck or are too high or low in tier to play ranked with then I'll play normals with them instead of ranked on my own, but I actually rarely even stay logged on if none of my friends are also on, there are just better games to play by myself lol
So yeah again not saying the way you think is wrong, it's probably more common then the way I think, just wanted to say that there are people who actually do really like the benefits for playing with friends.
However do I still want soloQ back? Fuck yes! I miss ranked 5s as well as no more then duoQ'ing in soloQ, Riot really fucked up dynamicQ by making it the only option, if they didn't remove the other options and try to smash them all together then dynamic would probably be a good thing people enjoyed.... instead of something almost everyone hates :P
