I agree but instead of removing them I just think they should be relaxed.

Mainly because yes there are a lot of jobs now and if you don't raid, you can only gear up probably 3 roles maximum to tome BiS before your gear becomes obsolete by x.2 or x.4 patches

It would be nice to be able gear up tanks, healers DPS AND one more DPS role, or all the melees within the melee role

having the tome limit to 900 instead of 450 would help a lot for that
