Love the 6-man party mod, and will never go back. One thing I have noticed: if you have a 6-man party (1 custom, 5 original) during some of the initial Grove encounters (Goblin Prisoner, La'zael's Interrogation, etc.) sometimes the game will glitch on the after-conversations and require a reload. Other than that, some of the tougher fights are made easier, and I love it. I may even look into the max level mod.
