Look up Galshiah's Character Development. I forget specifically how it works, but iirc it makes leveling up sort of happen in the background based on the skills you level up. --- ...and that's how I came to be known as the Flourescent Haberdasher.
Galsiahs is one of the most popular ones, but it's more trouble than it's worth. In its attempt to "fix" the leveling system, it ultimately just replaces the old flaws with new ones. There are safer, simpler alternatives that don't implement as much complex scripting.
One such alternative is Madd Leveler, a relatively straightforward mod. When you raise an attribute's skill a number of times, said attribute automatically raises one point. It allows for more well-rounded progression and eliminates the need for multipliers. Furthermore, you can edit the rate of progression, as well as level caps, fairly easily. --- "Don't blame me, blame society!" -Carl Johnson
Why would you need 384763495879 strength? The game is unbalanced enough as it is. 99-100 strength is enough of dominate everything Morrowind can throw at you.
The fact is, every leveling mod is going to have issues, since the leveling system is such a significant part of Morrowind's scripting and gameplay. It's simply a matter of balancing the pros and cons of each mod.
Madd Leveler isn't "trash" just because it isn't perfect. --- "Don't blame me, blame society!" -Carl Johnson
Why do you have to max your statistics? That's really not the point of WRPG's.
Partially fixed that for you, but you had it right.
Ultimately it's up to the player as much as I discourage min/maxing. GCD is your best bet. Linora's Leveling Mod also works great as a massive improvement on vanilla while keeping the overall system intact. It's like.....15 variables changed or something crazy but it makes a difference. --- http://i.imgur.com/9e7M1.jpg
I tried leveling mods, and found they made the game pretty dull. So now I just level as I go, and don't worry about maxing stats.
It should be pointed out that there are some mods, such as Lothavor's Legacy, that conflict with leveling mods. --- Why shouldn't truth be stranger than fiction? Fiction, after all, has to make sense.--Mark Twain
