well, off the rip i can give you a reason why its reportable. You are clearly unwilling to be a team player right from champ select, and i can see how "top or feed" can make a lot of people upset. Second, and almost as important as the first if not more, you really need to practice the other roles. Learing all the roles will 1.) give flexibility in champ select and help your team 2.) it will make you a better top laner.
How does knowing how to jungle, mid, adc/support make me better at top lane?
If you learn those roles, you will have an idea of what your team is trying to do, what the enemy team is trying to do and can predict enemy movement.
Jungle:
If you know the jungle routes, you have an idea of where they started, where they are going. You will be able to identify lanes that are prime for a jungle gank and have a really good idea where the enemy jungler will be headed. If thats your lane, you know you need to reposition to avoid getting soul crushed. if its bot lane, you need to keep an eye out, ping a warning for bot lane, and have teleport ready to turn the gank around and get that dragon.
rinse and repeat for the other lanes.
