Invisibility for the Town Hall.

Here's my IMHO, I think it should stay as is... I once had a battle where I needed to destroy Elven archers, and there were 6 slots with 100 of them each (neutral army)... if it weren't for invisibility, my entire army would have been wiped out, and there would have been no one left to attack the enemy... I divided the "hoods" into 6 for each slot and immediately used invisibility, while I was blasting the elves with enhanced shock... I barely made it in time... besides, this allows you to come up with a lot of tactical tricks, and I think that the fact that they can no longer shoot after acquiring this ability more than compensates for it...
