One of my favorite things about Oblivion (about any MMO that I've ever played, really) is the ability to work my way up to the highest possible level in every skill, and of course, benefit from the abilities acquired from reaching said levels. Given the amount of perks available, and the respective amount of points gained, even up to the highest possible level, the current system seems to completely disregard the desires of the player wishing to accomplish everything there is to accomplish. I believe something along the lines of a 'trainer' to purchase points for a moderate amount (likely somewhere around 3-5k gold each) after maxing out one's level would make the most sense. I can see no reason to not allow a player to make their character as powerful as they wish to, provided they're willing to invest the proper amount of time to make it so.
