Personally, i like the TES system of "you are how you play" which was, imho, properly implemented by levelling mods and consider it a much better "fix" to the default system of optimizing your multipliers than the health/mana/stamina thing they have for Skyrim. For those who may not know, the mods i mentioned adjusted your attributes according to skill increases automatically so you dont have to think about optimizing anything. This means if you fight with weapon and armor a lot, you become stronger and tougher, mutter spells constantly, you have increased mana, run and jump all day, and get more stamina. Makes more sense to me than swinging a hammer all day and still possibly increasing mana at level up.
THIS IS NOT A THREAD ON WHICH SYSTEM IS BETTER. So please dont derail the thread by arguing for one or the other. I made the above description of OB mods to see how it could possibly be simulated for Skyrim. I'm thinking of this:
1) disabling the option to choose to increase Health, Mana, Stamina at level up like the multipliers were disabled for the OB mods
2) tracking skills which may be considered to affect the 3 and raise those automatically i.e. weapon skills increase health, magic skills increase mana, stealth skills increase stamina
#2 could do with adjusting once we know the actual skills and how they're used. also, it would be better if skills affect more than 1 new attribute. so armor skills could increase health more and stamina less, casting could raise mana more and stamina less, etc.
also, im not sure how carry weight is affected without a strength attribute or move speed without a, well, speed attribute but skill increases affecting both could also be tracked.
