Should I switch to other class when my MSQ progress prevents me from level up?

I completed a normal quest when I got home and got 0 EXP for it. I was at like 0/850k or so. I then decided to try the next MSQ and as soon as we started fighting mobs I was getting EXP again. I guess that fixed it as I get exp for everything again and was able to get to 53 last night. I completed the first set of 19 quests after the ARR story is over out of the 100 or so needed to start the next expansion but I think I am going to be 60+ just from doing roulettes between quests by the time I get to the expansion content lol

Ah. I think I figured this out. Level 50 quests are considered ARR endgame content. A lot of those quests will not grant XP as a reward because the cap used to be 50 so there was no point of getting xp.
