I am running a party of six currently. My two extras are Bryanna (the sister of the True Soul killed by the owlbear) and Cyrel (the merchant dodgy paladin in the Tollhouse). Made Bryanna a ranger and Cyrel a wizard. We are currently in Act 2 (the Last Light).
Can't swear on it but I think this mod may make a full custom party doable.

I don't feel there is a noticeable game balance problem as I use several mods which make things 5e/RAW (playing on normal).

Thanks for the tip, will look at this mod. Can you give a list of the mods you use for making the game more 5E RAW?

Right now my biggest complaint with modding is with multiplayer. I do not want mods for the multiplayer game we are running. I have seen a few work arounds but would love a single, comprehensive modding tool that had an easy option of enable or disable all mods for quick choosing of how you want to play.
