The reason ppl wanted their concept to be SSR is so that their design is not hampered by their rank. There's a reason why DW rarely ever release new R-level servants nowadays.

Trust me, designing a 3-star servant is harder than it looks like. You have to think of how not OP their kit is compared to the rest, which will definitely bogs down some of the concept you have in mind.
