Recon and Guardian inherent bonuses include an attack speed increase for bombs..isn't that useless? I could be wrong especially since testing hasn't started yet but I don't remember the swiftstrike buckler (which gives ASI High to all) helping with bombs.
I am NOT a tester so take this with a grain of salt
Just the animation, look like your placing it down faster. Scares the knights away quicker if ya know what I mean. xD
