Banning should take into account actions within game
Okay it's just ridiculous that a person can just not say anything and feed or go afk and come back (and blame lag or bug splat) or troll pick champions and get away with it without any repercussions...Because Riot's system only punishes people that are more vocal about their actions. You can just do whatever you want and as long as you don't say anything rude or type anything in game you get a easy pass.
The past few games I had:
game 1: troll pick teemo jungle who KS'd everyone's kills, pushed their lane when we died then afked 3 times giving us the false excuse that he had a "blue screen". We told him to stop KSing or pushing and would and he did not listen.
game 2: troll pick nasus jg and int fed and all he said was "lol" or "xD"
game 3: troll picked twtich top and roamed all game from level one.
and the list goes on and on from game to game and happens often...
These players dod't say much just come in ruin the game and leave. The worst part is you are just held hostage for the entire 30-45 min of the game until the enemy stomps you completely because either the troll will not give in to the unanimous vote or one other person will just not want to quit.
This is just plain wrong. How can you expect anyone to play with these conditions? The system should allow reports with option of attachment of the replay or even a portion of the replay (if the servers cannot take in that many full replays) which we can crop to include the clips in which it clearly shows the person in question is trolling then followed by a permanent ban.
Like this is the reason the game has a bad reputation. Swift and hard justice is never served.
I know everyone is gonna downvote this right away it seems to be the only this the people on here do when you say something logical.
