I would say Tien's eye is the result of a template, much as super saiya-jin would be a template. It is the result of him being an advanced human, isn't it? Like an enlightened master or something? It's never really been explained, as far as I have seen.

Replace most magic items with limited types of intrinsic powers.

For example, a high level character would be able to Fly instead of having a ring of flying, would be able to haste himself for a bit instead of having boots of speed, would have super powered "Ki" fists instead of +3 flaming weapons.

Some kind of monk-cleric-sorcerer thing would probably work best as classes. Monk for the unarmed fighting, Cleric for the mass of buffing spells so they take forever and a half to power up, and sorcerer so they can buy magical attacks as abilities (or take lots of levels and get them normally).
