How did you level your tank?

[Yeol]

So how did you level your tank?

I found that levelling my tank is harder than levelling my main job BRD which 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..
