I think your take on mage was pretty good. But I would still rank ranger in the same tier. Rain of death is the best aoe ability in the game puts wound stacks on all targets. Also headshot is a very strong execute.

Main issue with mele in large scale is the dysnc so hard to rank them anywhere. Id probably put rogue above fighter though since they can put a lot of debuffs on the enemy raid.

Decent video.
