You shouldn't have to always hit a target an additional time to finish them off, mercy mode should work when you hit a certain number of HP you're dropped into it rather than all of your HP being exhausted and artificially stopped at '1' to put you in the current mercy mode.
I think it extends fights just that little bit longer that isn't needed, plus it allows more room for error-making since mercy mode isn't stationary and allows movement.
What would I want personally?
I would want mercy mode to make you immobile and rather than always being put into it before dying, it instead works like it did in MO1 where if the damage was high enough you'd instead outright die.
What am I proposing?
I'm willing to accept mercy mode working like it used to in terms of doing more damage than your opponent has HP, killing them rather than just mercy'ing them. Whilst they retain the current ability to move in it.
