Is that a reportable offense?
So, I was starting a ranked game with my friend. I was assigned top lane, so I declared I want to pick Mordekaiser, who is my main (I am basicly a one-trick pony). Our team support then asked whether he could go top, to which I replied with a no... He then proceeded to pick Mordekaiser as a support, despite the fact that I already declared him at the beggining - furthermore he haven't ever played Mordekaiser before, so it was obviously picked to f**k me over. I decided to pick Teemo instead. During the game he actually didn't rage or flame and wasn't THAT bad, though it was still pretty clear that he doesn't exacly know what is he doing. We ended up losing the game, because while I actually did very good with Teemo (9/6/8, dealt lots of damage and pushed a few turrets) I wasn't able to actually carry the match - And I am pretty sure that it would be very managable as Mordekaiser. Now I want to know can I report a player for something like that? Right now I am asking just because I am interested in it, but when it happened I was pretty tilted, especially since those were our placements.
