I have to assume this was intended since I double checked and in his announcement video it was the same, but why is the damage from SF Blade's parry degen so low?

That's a rank 1 7*, so I wouldn't expect crazy numbers but 14 damage per tick seems incorrect... compare that to the parry bleed of a 2* OG blade:

So the parry effect does less damage than the same effect of a 2* version of his original design? And then SF Blade has the little mention in his kit that says this degen only scales with base attack. I don't think any reasonable attack boosts could possibly make that threatening. What going on here?
