It isn't too significant a change, but one might as well note that with the new Dash 'n' Bash update, bombing received a small tweak, as in addition to a new animation on whiff, this amusing puff of smoke that appears above the knight, bombers no longer face the reduced movement that occurred when lifting a bomb. Additionally, though I cannot say that I was using this, we seem to have lost the ability to shield into charge as gunners and swordsman can, and shielding no longer cancels the bomb whiff animation as it did prior.
Also, though its benefit was so minute that it was barely worth mentioning, with this new change, the use of a Swiftstrike Buckler as a bomber is all but gone, as since it's main advantage was lifting and placing bombs to allow for faster movement, it now only provides half of its already meager benefit. Still great if you are not carrying exclusively bombs, though.
No.
