I was too lazy to search if anyone else had posted something like this so be sure to be extra rude to me if this is an old idea.
A dark spell should come out that when placed on an inferno tower, makes it's ability to stop healing powers neutralized for, let's say, 10 seconds.
Hogs will be viable at th10 again, base design will change (slightly) so you can't get both ITs with one spell. Gowiwi might be a bit easier to use at th10 and, best of all, it would help out th9's going up to hit a th10 a little bit if they get the spell.
