Unfairness

Now, Im not that great of a player, i was silver,but I fell to bronze 4 Due to some of my lack of understanding of the game, and although i have gotten close to being promoted, but end up falling due to bad games or trolls... this brings me to next topic why is that dodging in champion select a double edge sword, i have had so many game where i must chose, risk losing a game due to trolls in champ select or dodging Queue an losing LP and or having to wait 6 mins cause I was trying to avoid a game, another reason i don't quite understand the penalty of dodging is what if you are left with your weakest role( yes I understand that one must know all roles decently, but hear me out) if youre put in the role you dislike the most youre gonna play pretty shitty, and to make it worse the LOL community is... well dicks, I would rather have someone quit cause they didnt get want they wished to play than be stuck playing with a shitty support that dies 3 times in matter of moments due not being able to playing conjoined with his/her adc

what do you think?
