Red Mage is Range Combat? (Discussion)

[Khalithar]

From what little was revealed in that short clip, I'd say there's going to be some sort of combo system to it (this is guess work). But from the video and what was said, I think they'll use melee to build up their spell chains, jump out to become ranged and then unleash their main-stay damage, then when needed jump back in and repeat.

Then the question becomes this:

Why not just stay in melee range at all times then?
