I cannot argue whether or not SE's implementation of Blitz is good for the job, we don't have all of the information we need to make that claim yet.

SE seems somewhat aware of Bootshine being too strong, (though not aware enough to just change Dragon Kick's effect entirely) since they reduced the potency in the live demonstration from 370 to 300. However even with a potency nerf it doesn't stop my concerns that it will still be too polarizing because of its forced crit and Chakra generation still making it stronger than every other combo weaponskill, and Blitz will end up being irrelevant in favour of spamming more Buttshine.

But nah, clearly Arm of the Destroyer is the one that needs an upgrade. The skill that literally no one complained about.
