I consider the Legends mod so good it should be part of the base game, but it diversifies you instead of the content by giving you a class.

For example,: I can load up my Rogue character in troll armor and mince around with stealth, backstabs, thrown knives, crazy teleports and double jumps, or I can bull through in my usual relaxed way with my Priest and shield, mace, heals and holy nukes.

I wish they would reduce the item set requirements by 1 piece to activate the bonuses in the case of troll leathers accordingly for example. Doesn't matter in the long run as I can ditch them for banded now and just develop his natural stealth, but some more upgrade options would be nice for cosmetic and RP reasons and expand gameplay styles.
