I was playing Everquest this weekend and I forgot how fun my Magician was, and it has a very simple but rewarding loop of just a few spells. Aside from the pet aspect which has its own depth, one of the damage spells I have has a chance to buff my next damage spell or reduce the damage of my next spell. I can wait out the debuff timer easy enough and have to use another spell within the buff timer. On top of that I have a trait called gift of mana, that can proc anytime I cast that reduces the mana of my next cast to 1, so I can cast a very expensive shield on my pet with that up without worrying about mana pool. Things like this will never exist in XIV because they might cause one job to be 100 or so DPS ahead of another, so any kit interactions like this are just impossible due to raid DPS being the most important factor when designing jobs, not fun or style.
