Solo with friends is far to easy to do

I would bet you're one of the people who is exploiting this right now. There is a difference between playing against friends and working together. It creates a huge advantage for a group of 3-4 players in the same Solo match working together to eliminate targets. It's nearly impossible to take people out 2 or 3vs 1, unless your skills are far superior to the 2 or 3 your trying to take out. 

All your arguments are mute and pointless.
1. You can fix this issue you by staggering the queue time. Just random amounts between .01-.59 seconds would create enough variation that it would put friends in different games. a 1 minute queue is not terrible especially if it creates a fun and fair environment for everyone. 
2. Quit showing the champion so that it's more difficult to identify if you're in the same game.

If they don't fix this, then you're going to turn Solo into another team match type game. No one will play it truly solo, you'll just have groups of friends trying to queue at the same-time and get into the same game. 

It's this kind of garbage that's ruined EA reputation with a lot of gamers.  You have a handful of morons who think it's fun to cheat and they ruin it for everyone else.
