what I meant is that AS A CLASS, Supports benefit most from having high CDR over any other existing stat (except maybe mana/mana regen, for obvious reasons). Also, if you're another class and you prioritize CDR over anything else, you end up doing nuts for damage/squishy as balls and/or chewing through your resource bar with not much to show for it. On the other hand, Supports don't really care about doing damage for the most part, are squishy anyways because they don't get much gold, and have the resources to back up lots of casting (and lots of mana regen in their items to help that out even more).
