Need help between war and pld

[SeriousxSarcasm]

Anyway, back on topic: level all the tanks. You need paladin for provoke at least. Then decide based on what role you want. I would heavily recommend checking out DRK since it's so OP in current content compared to WAR or PLD.

Paladin is the default Main Tank in... pretty much all situations except A12 (and whatever other ones have the heavy magic damage). The times when Paladin can't main tank, people want a Dark Knight instead. You're fighting with a pool noodle, but in PUG content, much easier on the team to have a tank that can mostly take care of themselves.

As Warrior you're basically always Off Tank to take full advantage of their offensive abilities. They're essentially wasted as a main tank (and little more than an MP sink for healers once their cooldowns are gone). Keep in mind a lot of groups don't even bring an off tank anymore if there's no tank-swap mechanic, sooo you might have problems there. You will have to really practice where and when you need your cooldowns, because you don't have a lot, and using them inappropriately will reeeeally piss off your healers.

Honestly I recommend starting as Paladin. it's easier to learn, and more forgiving when you make a mistake. If you decide main tank isn't for you: go with WAR. If you want to stay as main tank: stick with PLD and/or change to DRK when you get the chance.
