One thing that could sort some issues is to auto change job when accepting.

So if you are levelling another class and have aggro, you could simply accept and the system would pick the first gear set available with the queueing job and equip it on you.

As for crafts and cutscenes that sucks a bit, since you cannot let ppl all the time they want to finish what they are doing.... imagina the trolls locking ppl in instances. It could just be usefull to give longer countdown time for ppl in cutscenes and crafting or let you resume them once duty is finished.

But that would be too expensive from a data pov I think.
