There actually is at least one unique item that can summon in EA already. A little out of your way to get but it's there. Not the same, I know, but I thought I'd mention
Which is???
Seriously but most powerful class in PoE is priest, a caster :O
Which is trash compared to NWN1 clerics...
NWN 1 Clerics, and 3er edition Clerics in general, are ludicrously powerful, being both a full caster, a specialist melee (3/4 BAB) and immediate access to heavy armor and shields with no spell failure. They also have both one of the best and most customizable spell lists with their Domains. In short, Clerics were nerfed to oblivion and beyond in both PoE and 5e without losing their shot at competing not only for strongest caster, but strongest class in their respective game.
They are fantastic tanks, good dps, the best supporters and overal super versatile due to their spell list's modular nature. Going from being the undodputably best class to just probably the best is a huge nerf. And one they had coming.
If NWN 1 Cleric is the standard you put for casters, not only do you want a system where non-casters aren't really viable alternatives, but most casters are pointless too because the Cleric does everything everyone does better.
