Valve should allow you to buy role queue tokens

I know this is probably not a popular opinion and maybe not possible because of the limited pool of players but I think valve should allow you to buy role queue tokens.

I hate having to queue the 5 roles. It’s Friday and I have a free weekend so I will probably play a lot of games and guess what, I have 0 role games.

But I’m also thinking this is probably the reason why we get so many core supports like alchemist pos 4/5… people don’t wanting to play support but they also need to farm roles.
