I have experience tanking all of Alexander: Midas Normal on both WAR and PLD and have cleared Sephirot EX, I just haven't been able to get my axe yet.
I have both WAR and PLD to 60 and can level DRK to 60 if necessary, though I am most comfortable on WAR and would prefer to play that over PLD.
I'm available Tue/Fri-Sun from 6:30PM PST and am available to start immediately. You can respond to me here or whisper me in-game.
