Many mandatory affixes in items

POE has a few affixes that make itemization for certain archetypes very one dimensional and boring. Specifically for spell caster, the overwhelming effect of + spell skill levels make gear without it completely worthless to pursue late game. Movement speed on boots and rarity in general are also pretty much mandatory to have, although rarity still has some play since its present in so many places. The attack side of skill fares better but +levels is still a bit problem there.

I think a couple of simple essence changes here can be significantly improve the itemization here. Update the perfect essence of sorcery to (5-6) for staff and (3-4) for wands and introduce similar +1 spell skills for amulets and focus. +7 and +2 can be those uber powerful high tier endgame crafts (maybe even a extremely rare uber perfect essence for +7 and +2 can also exist). Also make movement speed implicit please on boots.
