Quoted from tampa12:LOL Promium. I'm really not going to turn a pro into a prem but I think that would be interesting to see if anyone did that, since Todd Tuckey mentioned that in his video I thought this would make an interesting post. I really hoped to find someone that tried it.
It's sometimes possible to shoehorn in certain premium features into pro games, as long as they aren't driven by came code.
There have been significant efforts to add spinners into certain pro games, for example. There's a big thread somewhere about that.
