Ummmm... I hate to have to say this, but isn't the total number of stat points we're allowed really, [i]really[/i] low? I mean, EMIYA had a total of thirteen when you added up his stats (not counting his NP) and he was acknowledged as having the [i]worst[/i] stats in the entirety of the Fifth War, surviving only by his sheer skill. Even Medea, the second worst Servant next to Assassin, has a solid 15, 20 if you count the A+ as 10 instead of 5.

I'm just saying, for any legend worth its salt, this seems a tad restrictive and makes the Servants look kinda weaksauce.
