Not to beat a dead horse here but Marauder into Warrior overall is a really solid experience. Yes, overpower is a conal instead of a circle, but having played WAR since ARR it isn't that big of a deal (granted, when i leveled originally the alternative was Flash, of all things). Warrior gains a ton of great mitigation abilities (equilibrium is a solid heal, raw intuition is vastly underrated, nascent flash is really close to busted), and WAR is the first tank to get its death defying ability (holmgang still comes at 42 iirc).

WAR does have some issues, don't get me wrong, but most are very minor and are really only affect the offensive experience, but whenever I play WAR i feel pretty close to indestructible.
