Is it really that bad? LOL.

Even with we knew that DW and TM won't do something like that combo NP is actually plausible under idea of fan-made Servant. The problem is what kind of advantages make it worth and fair of consuming 2 x 100% NP gauge and having them; also the Servants with combo NP better have some of their skills effect locked without each other presence.

On one of gacha games I played, the devs. designed combo ougi units really good. Both of them firm as individual unit but you can only access their "high rarity skill" if both are present.

I myself have idea about this combo NP units.

Might try make the Servants pair to do it later, for now from DI and its event first.
