Your new support items have new abuse cases!
Midlaners now take it because so long as they stay below the 10 CS per 5 minutes mark, they will make more than they would by straight CSing so long as they only take the cannon & melee minions. Maybe buffing the cannon minions' worth wasn't the wisest? Idk, it seems like it makes all support items abusable when 75% of the gold in a wave is in a single minion.
The cycle of buffs and nerfs continues.
Support items get buffs, everyone else gets them nerfed.
