Support masteries

This is coming from a lower elo support player, so hopefully this isn't me just making mistakes. I feel like the new masteries e some support have a distinct disadvantage. Its mainly in the middle tier. Many supports need cdr, as to peel or engage. With the CDR so high up the tree, if you want one of the keystone masteries, you have to take one from the middle tree. The only good support one, in my opinion, is the windspeeker's blessing. But, this doesnt work on some support, like thresh, leona, or braum(just as some examples), who use the cdr to trade and fight in lane. I was wonder, would it be a good idea to move the CDR mastery lower down in tree? This is coming from a support. I do not know what other laners think about the CDR mastery
