45% mastery cdr not working as intended
I have been using this mastery and even rushing full 40% cdr and when i cap out it switches between 40 and 45% constantly and most of the time stays at 40% so i dont get any benefit from this awesome mastery. please fix this bug. thank you. ^.^ i have video proof if need be. but its pretty straight forward. it is not always on and most of the time stays at 40%
EDIT: So I did some more testing, and I can most games get 45% cdr with no issues, but only occasionally does it waver back and forth. I now am making sure I have 40% cdr from non masteries and it has helped consistency. will do more testing tomorrow. the mastery does seem a bit buggy still though. I will check tomorrow night if I have anymore issues.

only grants 10% CDR now. However if it took away 15% then something is very wrong
were my items with cdr
