if Zoe ever needs to be nerfed...

People always complain about her W having "no resource" and "no cooldown" but they always forget that it does have a resource, spell shards, which she can only get if you use a summoner spell on her or she picks one up from a minion (which you can punish her for), and it has a cooldown in that if she uses one of her own summoners, it get's put on a minimum 3 minute cooldown, longer than almost any ultimate. Even with shards, once she uses her W she can't get another shard until at least the next minion wave, usually longer.

Maybe remove her ability to cast summoner spells so she can be somewhat playable without breaking her with the slightest buff?
