Brainstorming a setting for a Tier 4 classes only game

[Doctor Despair]

If UMD was a justification, you should discount it in this setting -- arbitrary magic item crafting won't be so easy to come by.

That's a fair point. I'd imagine that would knock down Psychic Rogue a bit; would that empower mid-level casters like the Hexblade or misc buffers like the Dragon Shaman enough to be considered T4 in this setting though? I haven't played either of the latter, but I'd imagine the Dragon Shaman healing utility would be more pronounced in a world without NI wands of cure light wounds to purchase...
