it kills me when people lose lane even though they countered picked.
i just never really got that. so enemy picks a champ, let's say jax. then you pick teemo, or malphite, and yet you get rekt. i'm not talkin about a close score, but literally rekt to the point where top lane already took inhib and you haven't taken a single tower yet. just can't get that through my head. i've never lost a lane 1v1 when i counter picked someone. it's impossible. even if i afk, and come back 15 minutes later, my lane is still pushed and i'm probably half way of taking inhib.
another thing that really grinds my gear, is when people buy zhonyas and never use it. like wtf? same goes with sightstone. you might as well invest in a worthy damaging item.
