I would definitely recommend Warrior if you're curious about venturing into tank land. They're pretty much the easiest tank to play at a base level. They have a very convenient aoe dps hate generator skill and access to Flash from PLD. Their rotations are very straight forward, no positionals and when doing content that involves more than one tank, Warriors can always off tank. I think warrior is the most forgiving when it comes to playing the class for a person with limited mobility etc.

Warrior does have a lot of off global cool down skills, but they're very manageable and some could even be macroed together to make it easier playing with one hand.
