Me and a friend are leveling our way up to 99. We just started a few days ago but our planned duo is MNK and WHM. I like the idea of monk tanking but i want some advice on Tanking at level cap but also tanking while leveling.

1. Should i avoid evasion? I know it will override my chance to guard but im not sure which is more valuable. Also is there a clear stat priority when it comes to tanking for Monk.
2. Which Magian should i build first?
3. Are there any specific pieces of gear (not magian) i should seek that are easy to obtain as a fresh 99.
4. What atmas should i hunt at 99.

I tanked as a Ninja on my old character during 90 cap so i know about abyssea and how the game works generally but i could use some monk specific advice. Thanks.
