Fill Main Role for Draft?

In Draft Pick, you have the option to select Fill as your main role. I personally love this - I like to practise my skills all over the map.

However, I'm notoriously bad at Jungle, even to the point of it being a joke between my friends. I know people who would also pick Fill, if it weren't for ONE role they didn't want to play.

So I have a proposal - why not have a role you DON'T want to play? If you pick Fill, then another role as a "Don't Play"?

This way, it would allow for players to stay away from that one role they're not good at. Like for me, with jungle.

Thoughts?
