Ideas for the survival of U.R.F. mode

I can clearly see an overwhelming hype for U.R.F. mode, and that people really want this mode to stick around. I like this mode more than Hexakill and 1-for-All.

However, if this game sticks around it will be boring. But I have my own ideas for solving that problem and would like to encourage other ideas.

So how has ARAM stuck around and remained relevant? Answer: it's random. People play, hoping 1. they get an OP champ (ie, Nidalee, Gragas, Ziggs, and ADC's), and 2. they get a better team,

So why not make U.R.F. random? In this, you could just do away with the perma-bans and keep the champs like Sona and Kassadin on a low-probility of selection.

AND/OR

Make U.R.F. mode a draft pick....this way, you would have a chance to counter the super op champs.

Now it's your turn. Go.
