With the 30 second cut in time, and the buffing up of wizard towers and xbows, air attacks are getting nerfed quite a bit.
My suggestion is to make loons a tad-bit faster. They are too slow (the slowest unit - speed 10). Even golems are faster with a speed of 12. Its just insane to reach to 90+% with no defenses left and you run out of time because the units are slow.
Alternatively, after all defenses are destroyed by Balloons, it would be nice to have them scatter in all directions rather than remain clumped.
