There should be a guarantee of getting one's primary role in Draft after several secondaries.
In Draft I'd prefer to que as Jungle/ support, but there is a glaring issue with it.
If I have Support as a secondary role, nine times out of ten I'll get it over my preferred Jungle role.
So if I want a halfway decent chance of actually playing Jungle, I end up queing with a more popular role in the secondary slot that I both enjoy less and am less comfortable in.
This results in some dodges and more games that I didn't really want to play, but got due to the gamble to actually get Jungler.
So this is my proposal, that every two or three games played with a secondary role in Draft guarantees that the player will get the primary role they que for.
This way players in such a scenario would be guaranteed to get their Primary role at least one third or one fourth of the time respectively.
