Thoughts on: New Job - Mimicry

Ok...not another job post. Going through Blue Mage Questline, I thought of Mimicry and what I would like to see as new job. Mimicry would incorporate what we seen so far. The main job would necessarily "mimic" abilities in battle but player would pre-load abilities in a mastery book (similar to blue) but the abilities and spells would be taken from all the jobs you've currently mastered...think sub-jobs (ffxi), job roles, classes (mage and battle).

My Idea is this firstly, you must have "All Jobs Capped" to 50 (Tiered structured 60, 70, 80, etc). You could pick and choose abilities from ALL roles. Similar to Blue you could also specialize in Tank, Dps or Healer

Armor's would be universal, except you can only equip your current role.
