How did you level your tank?

[Causality]

So how did you level your tank?

I found that levelling my tank is harder than levelling my main job BRD witch I just followed MSQ to level. As for my healer (SCH), I just spammed dungeons. I am doing the same to level my tank (WAR) but compared to healer, it's taking relatively longer time. Three or four runs were enough to get me one level but as a tank I need seven to ten runs to level up

Is the EXP gain for tanks low on purpose to make them do more dungeons?
Or am I doing something wrong..

Tanks get the same XP as everyone else.

You may have had Rest XP on your healer and none on your WAR. Make sure also that you have your food buff on while leveling for the extra 3% XP, and if possible the FC buff The heat of battle. If you end up in anything that syncs you under level 30, then throw on Brand new Ring for the Extra XP, you get it from completing your Hall of Novice training.
