Game Mode Idea: Trolololo

So basically the idea of the game is to have a player on the opposite team that works for you and trolls the enemy team into losing.

The game would go like this:

-Game would be played on SR

-Size 5 people each team

-Teams would assemble

-Players chosen as the "trolls" will swap places switching teams

-Champ select begins, picks come out as normal (except the troll will pick up Kalista)

-The troll can steal cs, steal jungle creeps, and use her black spear at the worst of times on allies

-The troll cannot feed the enemy team kills

-Players would then play game as normal, except -players will have to deal with a troll on their team -players would have the support of a troll on the enemy team

I'd like to have feedback on this. I think it would turn out well, but if you have any suggestions, don't be afraid to tell me them.
