@ Meddler, can you address the concerns that some players have on the new mage itemisation

This helped bring up concerns, why is there no diversity for mages?, why are mages being punished in terms of damage for building items that have a utility or defense while AD champions just build items such as .

1. defence why can't mage defence be easily accessible, are all uber expensive, IMO you have done nothing to resolve this issue. why mess with Zhoyna's CD ?.

2. Diversity why can't we have grievous wounds all the time like ad carries do, so sustain damage mages can have a chance against AD champs? why can't there be one or more items like this that don't stack with this or each other that offer different passives, like giant slayer on or (as nain contestable said in the link above) some of the items from black market brawlers to bring some diversity (Rite of Ruin, NetherStride grimiore, and Pox arcana )

why can there be more large AP items like Rabadons, why not reintroduce DFG at the same cost of a death cap and have the Damage increase % scale with level

I would really like an answer for this.
