Tanking, PLD/WAR or Nin/WAR?

[Ryan0617]

I want to be tanker in the higher lvs. But i am unsure of how complex it is to tank.
I mean, i have read previous posts on which tank is better, PLD or NIN.(Alot of arguing going on there!)
I understad PLD, higher defense and able to hold hate easier. I also understand there skills and spells.
Burt i am confused by NIN. What i mean is, they cast spells right? Ninjutsu? They have three levels as well? And they cost money??????
Can you please confirm this. I am not really short on money by the way.

I just want to know which would be of more benefit with a WAR as a sub (i do not intend to change this-so please don't say so) at higher levels, 40ish plus.

Please do not turn this into a PLD-NIN competition over which one is the best. I just want a clear opinion on which is better for the WAR as the sub job.

Oh, by the way, i am a Galka so would this be any good for PLD or Nin?

Best thing to do is read the jobs in each of their forums.

But ill tell you this.

Pld versus undead, fast enemies, medium fast enemies, slow enemies

NIN versus slow enemies
