I can't decide which tank to play! Help :)

[Noitems]

WAR and DRK are mainly built on priority. Skills like Nascent/Shake and The Blackest Night allow you some of/if not the best shielding in the game. They have rotations, but their skills allow for more flexibility albeit at less damage when played on the same skill level as GNB/PLD.

PLD and GNB are more focused on their rotations and are very strict to them. But that in turn gives them the highest DPS output out of the four tanks, but also hurts them badly pending on your fight with uptime not being met. They offer mitigation, not as powerful as WAR/DRK, but it is consistent. You'll almost always have a CD for either of them through Heart of Stone/Sheltron and be able to help your co-tank through Aurora/Clemency. However the main focus for the two of them is rotation/damage.

If you want a non meta look and a more personal one, play what you want.

Gunbreaker is the easiest to get to 80 since it's at a higher level, and your rotation can be practiced in full when you hit 76. I'd say leveling WAR/PLD is a great way of practicing the jobs and following the job storyline (More so for War out of the two). DRK starts at 30 but it has the most engaging storyline and it really starts to peak when you get Bloodspiller(Not as much as 4.0 days however due to TBN changes).
