Movement: This has always up until now been issues that may hold blm behind, no other jobs are really affected by mechanics as much as blm has always been.
Red Mage brings great damage, it has movement so mechanics effect it far less and also great Utility.
I only find to have mp issues if i am raising multiple players in the group, Lucid Dreaming seems fine thus far. It still should have it's own mp regeneration though
Sure i may not be right but i do predict groups will not be taking in blm or smn but Red Mage instead
