How do you guys think the magic system could be improved in ES6 over Skyrim? I believe that it could be significantly improved over what we had.

Hello and welcome to the Forums! For starters, adding more spells would be a big improvement, IMO. Skyrim's spells were basically just varying magnitudes of the same spells so having a greater variety would be be great.

We have a thread for discussing ideas/suggestions for future TES games: http://www.gamesas.com/topic/1596006-official-beyond-skyrim-tes-vi-75/
