Hi there!
Tell us what of those ideas you like most!
By no monster level I means something like: Bandit he always have 100 HP, 100 Stamina, 100 Magicka also got some constantly skill and abillietes like He can use 0 - 2 lesser health potions or something. Also he ALWAYS GIVES you about 50 exp. it's all about permanent numbers.
He go always the same loot rate like for fur armor 10% and steel sword/axe/mace 5% etc.
Why I like these ideas? Because it's make map more special. Like you got will almost all MMO you got areas for 10-20 level and ppl with about level 50 have nothing to do there. Also low levels player has no challenge at all. If there isn't monster level you can fight areas with Bandit whos you can kill on 5th level, but when you go deeper and deeper you could fight for example Bandit Thug whos is a lot stronger than other, but still got permanent numebers and loot. So in the surface of some areas exp low levels and deep underground higher level.
Now about loot. When you collecting your eq on low level or high level you will have choice what will you hunt to loot something. For example: me low level so go for badins for weapon and armor, next got for falmers for boot etc. Also when you got Boss you actually knows what he can drop. So when you got low level but you are skilled you could try kill some more difficulty monster to get better gear and also you can exp faster depends on HOW skilled you are not what level you have
Hope made my point clear and sorry for my english
