That’s true! The point I was trying to make was simply that players could also look left and right at the other members of their party when making their characters so that the entire group becomes more effective, rather than just optimizing on isolation. I remember treantmonk mentioning a story of a group of optimized characters facing a mindflayer. None of them had int save proficiency so one mindblast just rekt them.

Thank you so much!

Ouch! I feel for you. That must have been a very bad experience.
