Spy Mission vs Docs Mission

[Dr Clean]

Why Spy on Hokage/Kazekage/Mizukage Office missions gives less exp than Retrieve Compromised Documents missions? 

For Docs its 149k and for Spy its 74k... , both are Rank A missions, for both you will fail if you faint and the easier one (which is in my opinion Docs, u don't  need to wait 2 mins, just in and out) gives 2x more exp. If it comes to ryos Spy mission is giving only 150 ryos more (200 - 350).

The only reason I can see is that based from a RP standpoint stealing documents from an enemies base would be a harder, more rewarding mission than just regular spying. I definitely feel like they are more equal tho, spy mission is less then half of the exp for docs, it needs to be at least in the 100ks.

Ye, for both missions you need to get into kage building, and spying on kage room seems to be harder than getting some docs
