How has he not been?

Apart from encasing Natsu in that ice geysir in the fight against Mard Geer (which happened within an hour of him getting the new power) and doing as Erza told him (following orders hardly counts as smart), tell me a single smart decision that Gray made since getting IDSM.

He used to fight smart. Now he fights with just raw power and nothing else.

And don't even get me started on Gray patiently listening to Invel's monologue, instead of just pressing his advantage while he has it, or staring stupefied at Brandish instead of keeping his guard up.

We all saw how well those two "smart" decisions ended...
