Class restriction of equipment is stupid. There's no magic curse on items that says someone can only use something. Instead, give certain "Classes"/builds incentive to use items. A wizard has no reason to equip a Helmet that grantz +10 Physical damage, over a hood that grantz +2Magicka Regened per second.
:goodjob:
The problem with the "feeling unique" thing is that, although Oblivion seems to give you infinite options, it's only giving you three:
-Hit It (hey, lot's of weapons)
-Use a Spell on it (hey, lot's of spells)
-Sneak through it
If you take a look at the skills, they all belong to either http://www.uesp.net/wiki/Oblivion:Skills
Oh, yeah! Guilds! There are three MAIN guilds... one for warriors, one for mages and one for thiefs!

Since I like to out-smart NPCs and try to find a non-agresive way of solving problems, by persuading them, flirting or what ever, I find this horrible.
