What is Detonate? How is it even doing damage? The charges blow up to do the damage. It makes no sense. And what are we using to detonate the charges? Some sort of machine? Isn't that against the Guardian lore?
Let's do things this way: Scrap Detonate. Make bombs FINISHERS. Makes sense; Toss a bomb at the charges to blow them up. Much cooler, makes more sense, makes bombs useful, and gives Sabo true finishers like the other callings.
As for traps? I have no clue. But bombs as finishers makes the most sense.
