No. 2hr abilities(most) were for the most part useless. All were extremely underpowered for an ability that is on a 2hr cooldown. To actually have an ability thats on a 2hr cooldown and be worth it most would then say "Its too overpowered!"
I would prefer each job(when they are added) getting a 30min cd ability that is actually useful.
edit: They also lasted about 20 seconds? 30 at most for some jobs. It was a horrible way to implement an ability overall. In the end they just were used for brief fun every 2hrs.
