i tried to go for a speed cast on the wiz i created and and put all speed cast spells i found, but when using the the spells with the passive speed cast, i get 54% and not 64% like it should have been.
did i have done something wrong ? or is it just cap ?

Cast Speed buffs have a soft cap. Using this forumla:
1 - (1/(Sum[(1/(1-CDR)) -1] + 1))
You have two buffs each giving 20% cast speed reduction. Then the calculation would look like this:
=1-(1/(((1/(1-0.2)) -1)+((1/(1-0.2)) -1)+1))
The formule makes sure it never reaches a 100% but also never caps out completely. I hope this helps, even if the formula looks a bit confusing.
