That is a little to general and depends on what kind of ap you are playing. Vlad for example, CDR is AMAZING on him and is really strong. Anivia can utilise the CDR really wel too. Cassiopeia for example cannot utilise the CDR, dispite being a DPS mage. Her E is a static cooldown and her q only resets the dot, so CDR does not help it. She can only have 1 W on the field at a time, so CDR only actually helps her ult, which is always up by the next fight either way. This list puts her really high at the DPS with max CDR, but notice how she is also first WITHOUT the CDR, because the CDR does not affect her, she is just naturally like that. Burst Mages need AP not CDR (Generally), you really can not generalise it. Take the information from this page with a grain a salt, it is useful, but think IN THE MOMMENT and not generalise every single game.
