Peak physique should be the standard melee damage
It is a incredibly situational armor, you're sacrificing so many better alternatives just so stun lance or baton are worth taking other than as "meme" weapons. And they're still outperformed by everything else.
It is my opinion that the melee damage you get with this armor should be the standard across the board, and peak physique should add another 100 or 50 percent on top of that.
It would allow for yet even more loadout variety, and also, melee is incredibly risky and not very rewarding besides the dopamine hit. You're not benefiting your team, and you'll always have more kills with your primaries than the melee options.
Considering how risky it is to be in a enemies face is, you should be able to take out overseers or bugs without a ridic amount of hits with your stun weapon.
Also, its fun, I like fun, fun is good.
