If you're full-build + elixir, why take all the farm?
Hasn't happened to me in a while but I actually question the decision. It doesn't just happen in low elo (where I'm at), but also in pro play. Fnatic will give Rekkles all the farm even if he's at 6 items no boots + elixir and level 18, while the rest of the team is behind in levels and items.
I can understand the need to waveclear obviously outweighs the desire to farm in certain situations, like when the enemy is seiging. But when they're not, why hog all the creeps and jg camps?
