I have been searching for the patch notes to this era, specifically combat mechanics due to a debate I was having, and was hoping somone could help me with my memory and provide some factual resource(s) behind the answer. The question in regards is When casting a debuff on a target (Clumsy, Weaken, Feeblemind) to disturb a players spell cast who was already pre-debuffed (let's say in the beginning of the fight because it is commonly used in the openers), did the spell fizzle or did it just 're-cast' and re-disturb the target hence making it a viable disturb mechanism in PvP? The way I remembered it was the latter, by letting you cast a debuff as many times as you wish assuming you had the mana available and skill high enough to do so. Unfortunately, I cannot find a patch note or developer note that backs my theory up. Any help on if I am right or wrong would be greatly appreciated!
