I'm all for increasing the EXP from sidequests starting from SH. I did some basic math when looking how much EXP it each quest rewards with how much total exp the level you're on is needed, and it looks like each synced sidequest gives ≈2%, which can definitely feel like a drag. Especially since as solitonmedic said, there are lots of sidequests that have hilarious moments, and some help flesh out the world.
