The worst suggestion on this line is to ban the spell.
The Sorcerer is supposed to spam spells and harry his opponents. A sorcerer is the swiss army knife of classes. If something is working, as boring as it is - he should keep doing it IF it's effective.
If you are concerned that the player is using it too often or the spell effects are too defeating to your mobs, maybe it's not the player who should suffer. Maybe the challenge presented isn't enough to ensure the player is forced to think of a new strategy?
I think spamming flying creatures isn't to your advantage. But using certain available spells (ala Dimension Door) would effectively end SpamPittillwin. Now if suddenly all the mobs could DD that would be lame. Why not add some RP into it as well? A ninja could flip out of the pit. A mage could levitate out of it laughing as he does so. A 15 foot Frost Giant who martial arts movie style suddenly landing in front of the group who thought they had nullified a threat will have to rethink strategy on the fly.
It's a 10x10ft hole, if the Giant failed his reflex he could possibly make an acrobatics check to lay across the hole. (As it's taller the the hole this is conceivable to me)
A GM should never consider banning or disallowing something unless it's truly destructive to a campaign. A sorcerer spamming a spell shows a lack of creativity in GM mob presentation and scenario.
