As my Oblivion is sort of running on the edge of a kitchen knife, I usually wait a bit longer before actual playtesting new mods, sorry.

But if some people like that, cool. =/
Guess it all depends on your playstyle. I don't really think of it as forcing the player into a specific style, but more as an addition, an extension to the player's prefered playstyle. I'm personally not a fan of a "Jack of All Trades - Master of None" characters, so I narrow my class down to fullfill a rather specific task in combat etc...
If I knew anything about scripting, I'd try making something similar to this but for races instead of birthsigns.

On topic: A random comment out of nowhere which I just realized: I'm a bit saddend to see how you benefit the Warrior's Blade, Blunt, Heavy armor. The mage's magic skills and magicka. The thieves/assassin related stealth skills, ... You get my point? But not Marksmanship on it's own. I've no idea where, how or if it's even possible to still implement it, but I thought I'd mention it and let your creative brain work again.

Keep up the great work!
