People and wards.
So why do people think warding is ONLY the supports job. just had a* (Ranked)* game and the chat looked like this in champion select/early game.
Me: Hey they have a panth jungle, we need to keep dragon warded early.
Team: it's the supports job to ward.
Me: Umm, i can't keep dragon warded by myself at level one.
Team: get sightstone.
Me: at level one? sigh
Team: Shitty fucking support doesn't ward dragon.
(This whole time corki had not used trinket ward in lane or in river.)
TLDR: everyone should buy wards.
(Or at least use the ones they have.)
