Zoe
I really think there should be a one or two second delay before the spell bubbles show up where the opposing champions used their spells at for Zoe.
This way, when you flash, Zoe can't immediately pick up your flash and flash after you, making your flash spells completely useless in her presence.
Also, for minions dropping bubbles, I think they should only drop spells that the current nearest opposing champions have, intead of dropping ridiculous, OP at that level, random spells like gunblade or redemption at level 3 or something.
