Having played around with this at level 80, even after the buff to sword spec, axe spec is far superior (and this is on a human so sword even has an advantage). However, since you are buying a grand marshal weapon, I'd HONESTLY buy the claymore for ____ and giggles (is it ok to swear here? will check rules in a sec). The grand marshal axe looks like garbage and making a 60 twink is at least half about looking like a badass. But yes, axe spec IS superior to sword spec even at level 80 where the cards are stacked against crit and crit damage (resil douple dips to reduce crit damage).
For those of you arguing about enchants, berserking is far superior to any of the others listed, even in the offhand as TG, berserking yields more average attack power than 110 (somewhere around 130 I believe?).
On the one hander you probably want mongoose just for survival, and the shield is debatable. Many will say 18 stamina, but what they don't know is that unless you are healed to full after you equip the shield, you won't gain ANYTHING from that 18 stamina. And if I get healed to full then what is the problem? This is why I recommend 12 resilience to shield, those 12 resilience will help you even if you don't receive heals between equipping the shield and taking damage. Now this does change if you have the shield equipped before you go into combat, in which case I'd stick with the 18 stamina.
Now for your prot set, I would go with the 18 stamina, but probably berserking to weapon, the more attack power the merrier!
