Dodging (and playing another game)

I cannot describe how tired I am of having a champion I really want to play, locking it, and with 30 seconds to go someone dodges.

Next, I get into a new lobby. Guess what? Enemies ban my old pick that they saw last time.

I really don't think it would be that difficult to implement a function that prevents the same players being put in a lobby post-dodge.

Not only does it bother me, I know it pisses off many other noobs and possibly even higher ELO players where the queues have fewer players... Maybe this function could be edited based on the amount of players (Ie: if 20 diamond players are queued, lobby starts and ends, it mixes 5 of the broken lobbied players with 5 new players... I'm just making something up on the fly here, smarter people could make a system but the point is, it doesn't need to break the system if only 12 players in an ELO are queued)

My point is, I despise everyone that intentionally dodges because you dislike a champion.

Any thoughts on this subject in general? Complaints? Deep affirmative affection?
