Do you have any videos of how to beat the more difficult fights without cheesing any of the larianisms with a solo character? (height/los + poor enemy pursuit AI, Barrelmancy, etc)
Nope. You can check out youtube videos of others though.
Correction : nope, that doesn't exist...
Shoot/hide/shoot/hide/... is also an another way to cheese the game and to easy beat the AI... The first 10 solo playthrough are full of this and/or of other things I talked about.
Don't get me wrong, I'm glad if you enjoy this... You're free to love having common god mode cheats everywhere in a strategy game.
But if it's "so easy to beat the game with a solo character", that's because the game is poorly balanced... Whatever you enjoy it or not.
