Well, the thread was examining the spammability of as such, not overall viability of heavy CDR. Nonetheless I believe that CDR is okay-ish on the champ.

You are of course right that only those two abilities need CDR, however DPS of still benefits from CDR as long as its CD isn't static. E.g. 40% CDR means flat DPS increase, (almost) regardless of base cooldown's value. The only restriction can be the cast animation, which means less space for "stutter-casting".
