Really depends on the community. In general there are some times builds are oppressive for others and not fun, the huge beta that deepkin do can be hard to weather, but it's certainly something which can be countered. One way to mitigate this is to swap armies. Sometimes seeing the weaknesses from the other angle can help. Consider this, could you beat your army with their army? Would that requires different units, tactics, or both? Do you guys discuss tactics outside of games?
You can try bringing different lists.
Remember that both sides want to have fun.
Good luck finding that balance of crushing and enjoying for all involved.
