I've been campaigning for SAM tank for awhile now lol.

I played SAM pretty heavily in XI and I enjoy the aesthetic alot.

They could do Rune Knight for a hybrid tank. Viking for a more traditional VIT tank... although WAR basically fills that aesthetic.

Red Mage or a variation on Blue Mage would be an interesting mage tank idea. Theres quite a few defensive monster abilities that could be used.

I'd agree that making an evasion tank would be really hard to do in the ruleset that they have set down on this game.

If they wanted to do a unique look though they could do a variant on jobs with a more middle eastern feel. I was hoping PLD would turn out that way but they went full on European knight with it.
