Okay ... I can understand someone that just isn't good, but learn the map!
Poro king is essentially ARAM, except the spells are fixed, and the king (love the blind pick, BTW).
That said, and that so many people think ranked is the only mode that matters, they ought to either stay off the map, or learn the map. So many times you have people thinking they can dive alone ... or go jumping ahead of the rest of the group ... and tanks that just don't play as tanks.
It is a pain. Having a heimer that doesn't deal twice the damage as the rest of the team ... he isn't zoning with his turrets. Tanks that don't build tank (you can tell, they are heavy on offense, light on defense). Supports that could care less about doing their role, and want to carry. Collectively, I say to everyone that does that: Grow-up! League is NOT about the individual getting a good score, it is about the team winning. If you think it should be about you, go play a fps, not league ... because with H.A. and blind pick, the team that cooperates is the team that wins. Doesn't matter that the champion that has the most kills overall, or the highest damage to champions ... if your team loses, YOU lost.
