Based on playing with Azen, I'd say this is far from a terrible build for her. Her farming really ramps up fast with this build since she's got really high damage on her skills, so its pretty easy to get to that glacial shroud at least, if not the full frozen heart. So yes, you could be getting more CDR and getting off a new Light Binding an extra 2 seconds early, but you end up trading a couple hundred in damage each time you lay down one of your attacks.
And LOL at her not having enough mana regen with this build. DRing + PhilStone + Tear = plenty of mana regen through the mid game. By the time you turn the tear into AA Staff, you should have enough mana that you won't be running out unless you are just sitting in a lane spamming abilities forever.
For that matter... Azen is going mad positive with this build at 1800+ ELO with Lux. Not trying to be salty here but what exactly is your elo again Jaz?
