It sounds like Yendorian Tales III is a shitty game.

You said you played DD, but why would you revisit old spots like the crypts of Aleroth again?
You would easily kill every enemy with one hit and you would get no xp. If you played through DD you should know that there are more than enough enemies and that larian isnt forcing you into taking certain talents. Sure its easier with restoration but get the skill like 2 or three times for free and you can win without it.

I cant really understand why its disappointing its like being disappointed when games like diablo or titan quest are not turnbased and have only fight-based skills.
