It gets very repetitive, but if you're solely using it as a means to an end for schooling, then it's manageable.
And even a full time 8x5 or 4x10 truly only takes maybe 2-4 hours to get things done, so then you have the rest of the time to study.
My career is in a sort of glorified data entry (GIS for a utility company), and it's super relaxed most of the time.
I actually want them to step away from 5e/DnD in general. I loved DOS2, but I agree with another commenter that the vast swaths of elements made things challenging in a frustrating way at times. Not that that shouldn't be a tactic to be used, but it definitely was egregious in DOS2.
5E is just... A fuckin mess when it comes to balancing the game - said as a long time DM and player. There are so many things that just irritate the heck out of me with the system that can't necessarily be balanced with a video game slapped overtop of it. (Not to say Larian didn't do a good job with what they were given, but still)
That being said, I am a total fanboy of Pathfinder 2e and the way things are balanced there, and I would love love love to see a CRPG under those rules. Especially if it was Larian-levels.
