my emiya is fully leveled, i just have much higher priorities when it comes to skills so they are level 1. and unless i get a second emiya my go to AoE archer will still be nobu cause nobu just seems to do more damage than an NP1 emiya.
i suppose it doesn't help that i spend most of the down time in this game leveling servants for their strengthening quest's saint quartz these days instead of skill ups. thankfully most of the ones left are low star servents now.
