I agree on the Jump Spell. The difference between 20 seconds and 40 seconds is huge in terms of effectiveness. If you don't put it down early your troops will start running away from it, and if it only lasts 20 seconds it may vanish before very many of your troops have an opportunity to use it. 40 seconds seems like it lasts plenty long enough to get all of your high-damage troops to the center of the base.
