Ah, this has all been quite helpful so far! Thank you!

I do plan to get all classes to 50, so no worries about the cross class skills needed. And I had heard that it doesn't REALLY matter which class you go with for endgame, but some would tend to be more useful in certain situations.

I am new to tanking in general, I did try some guildheists with PLD to test it out, and I seemed to do okay there. But as others have said, WAR just seems like more fun to play. Plus I like the way my Highlander looks running around wielding that ax. lol
