This is assuming debuff design doesn't change. As far as I understood their plans, the current debuffs being additions to normal spells is "temporary" until they introduce a real debuff class. Even if said class would have some damage skills, they would have to balance them to deal less damage to offset the future use of debuffs in raids.

The problem with leveling would then be, why bother casting a debuff that takes 1% of mob's hp if the mob will die in less than 10 seconds anyway? Why not take a class that can push that to 7 seconds instead of the debuffer that makes way too little difference?

What you are saying would be true if we had longer battle times - then debuffs would be able to make some real difference. The longer the fight, the higher the impact of debuffs.
