Zigg's tower execute seems a bit too strong
His Satchel Charge executes a tower at 25% health at rank 1, scaling up to 35% at rank 5. Dafuq?
EDIT: Video of example here: https://www.youtube.com/watch?v=hqbg8ZVotSA
And the towers have an indicator icon of when they're executable too. Just wonderful. ( ._.)
