EMIYA really isn't a "weak" Servant outside of UBW. I'd even go as far as to say that UBW is only really formidable as a tool for him when it comes to the actual projection rather than the outright activation of it. What you're showing there is one of his Broken Phantasms, which is pretty much his trumph card, so it's a pretty unfair comparison in that regard. For example, Arash has demonstrated he could break down Ozy's temple walls (equivalent to an A-Rank NP) with a barrage of 10 arrows. 

Still, as a Rider Class Servant hailing from a land with quite the distance away, I would just recommend cutting it altogether. Class containers exist for a reason and this does enter Archer territory pretty heavily. The character is already rocking 2 other NPs, so I don't think it's too warranted. 

Another question I have is why Tseneglegch is ranked at A. From what I can see there, it's not really comparable to things like Divine Beasts, which also makes me question the Riding A+. A master of "any horse" still isn't on the level of someone who can ride Phantasmal Species (which, judging from the description and A+ Rank, I would have to assume is the implication here since otherwise it'd have the standard A-Rank clause for Riding listing the exception).

Since we're probably really close to starting, I honestly suggest you reconsider how Legacy of Gérard works. Right now it's pretty much equivalent to a Mystic Code without much formidable going for it. Some secondary effect upon hit or something would probably do it good (within reason).
