okay, for all those that ARAM should not be balanced, and you have fun winning when it isn't ....
Why don't you just play coop vs ai?
You can show about as much skill, i.e. none. You obviously don't care about it being a challenge.
Of course if you think the dice roll is the fun part, just flip coins.
H.A. is the only map that has any possibility of fun. The rift is boring beyond belief. Who cares about farming? If you are solo, it means nothing that you meet a team that can communicate and gank. Treeline is only marginally better.
So how do you balance random? If you can't figure it out in 10 minutes, please don't tell me you are a software engineer. There are plenty of ways to do it. Just because you can't figure it out doesn't mean it can't be done. So if you can't figure it out, don't complain, don't grip.
If you don't want it to be done, why not just play bots?
