Azir

They allow AP champs to damage turrets now with auto attacks so it was just too strong with Azir using his w on them too.

Azir = overloaded - they got rid of free AS from CDR, bonus MS to allies, W dmg to towers, knockup on his E... Also all mages buy some form of mana sustain, but the golden boy for LC$ big plays can have 70 mana Q, 40 W and 60 E, so he can spam without going oom and buying Nashors instead of mana item.

So, the new nerf...I main Azir and I didn't even know his W did damage to turrets? Very confused here.

if you didn't know this then you don't main azir

Imo I don't think azir nerfs did much to him. It just hit the little things like the w on towers and 20% movements speed. I only have a small problem with his ult being 3 seconds but I can get used to it.
