So, levelling in TES has had some... interesting... design choices over the years, from the weird counterintuitive attribute-maxing minigame of major and minor skills in Morrowind and Oblivion, to the much simpler but arguably less-interesting system in Skyrim. And then there's the contentious issue of level scaling getting its oar in, too.

What would you personally like to see implemented? Where does modern game design stand on the issue? Is skill-based levelling still a sensible idea, or should we be looking in a different direction? (Generic XP? Something else?)
