I also had to slow down on raiding due to work/school.
However, considering the difficulty level of this game (pretty easy), compared to other MMOs out there, you can still raid. I have yet to reach a raid that I couldn't learn fast or keep my dps/heals up to speed in. Surprisingly, pugging a raid isn't so bad as long as you kick people when necessary. I'm also on Levi server, which might make a difference in the skill level of people I get in parties, but I have no clue don't quote me on that.

Anyways if you still don't have the time to raid, there's plenty more to do if you enjoy the world. All the primals are fun and can be done without a static, assuming you know what you're doing. Relics, Beast tribes, stock up on all those mounts. To be honest what keeps me going is running an FC that doesn't raid and just chills, it's nice when your crafts and such actually are being used for something right away.
