I think the abundance of CDR has led to damage creep

CDR should be on AP items and not on AD items.

AD champs CAN fall back on auto attacks and tend to have lower Cooldowns on abilities.

Casters (AP) champs have longer Cooldowns and have ZERO damage on their Auto attacks (that also are slow AF)

If a AP cant kill and AD in one combo the AD WILL kill them just because they can auto attack them to death while the AP combo is on CD.

Its a Problem with the game.
