If you scrapped and started over, you'd probably end up creating LoL. LoL might even be more balanced, I don't really know, but considering how much less complex it is it very well could be. But competitive LoL seems one of the most boring things out there, and I've been repeatedly told those games often boil down to lasthitting. But hey, that takes skill.
If you didn't create LoL, what would your game look like, then? It's easy to design one, so why don't you give some pointers? How do you make a game that is at least as interesting as dota, but isn't dota, but is more balanced than dota? Don't think it should take you more than few minutes to do better than mushroom-eating Icefrog did in 7 years (+ whatever the other devs and Valve staff did), so I'm all ears.
