Gotta love how you shift the blame to me.
He did not ask for Akali, he did not intend pick Akali. He did not communicate he wanted Akali at all. He just started his bs attitude once i already picked and locked her in. I did not intentionally pick her just to screw with him, i intended to play Akali that game. The whole point was that he though he owns Akali as a champion and that he alone has the right to play her and no one else.
The guy didn't lose his lane because i didn't give him Akali. He wasn't on his lane at all because he was making sure i lost mine. He followed me throughout the entire game in my jungle and taken CS just so that i lose as well. That was very deserved in your book and justified, right?
I don't really care if your win rate is 200%, if you didn't communicate to your team what you wanted to play, i see no reason why my gameplay should suffer for your benefit. You're the one not paying attention, don't blame it on someone else.
You do not lay claim to champions just because you main them. I main Morgana too but i don't do this when she is picked by someone else. I either make an arrangement to trade or just play something else. In worst case scenarios, i might dodge a queue, if i particularly feel like playing Morgana and no one wants to indulge me.
Looking at his match history, he plays other champions mid and for that game, he obviously wanted to troll for no reason. Looking at his match history, this wasn't the first game he trolled in this manner and out of 20 recent games, he has at least 4 where he trolled.
That's an astounding 20%. Doesn't really matter what his train of though was, i and everyone in the enemy team reported him.
I also just want to mention that was the same attitude with one Rengar main in my game, where he'd done the same shit to us and we reported him. Riot banned him. Except no one took his Rengar but he deliberately threw the game once our jungler Nidalee, did not give him Rift Herald buff. Because he was also a selfish jackass who think everything in the game has his name on it.
