I'm playing on Master with the following mods and both DLCs:

Nightmare - Enemy Spawner Mod - (More Enemies)
Fixed Followers
More Dragon Loot



Now I'm looking for a mod or mods which balance what I have. I'm looking for enemies that scale with me or have better levels than they do in vanilla this will counter the mods I have in place to help me and keep the game challenging. I'd also like to mod which slightly makes Werewolves better (not to over power them just to keep them playable against levelled enemies) - An increased weakness to silver and the addition of more silver weapons in the game would also be acceptable.

My goal is to create a game which challenges me continually and rewards me when I take on hard challenges. I'd also like a game where I don't have to self gimp myself by ignoring enchanting, I'd like to HAVE to use enchanting and just not abuse it.

This probably seems like a tough order but I would appreciate any mod suggestions which may help me out.

Try one of the combat mods. I find that enemies who fight smarter are better than just enemies that hit harder and are tougher to kill. My preferred combat mod is http://skyrim.nexusmods.com/mods/3646
