I never, in my post, stated that anything in the c store was game breaking.

However, giving players 2 character slots (3 with a klingon faction when a character reaches rank 5) and then charging for more slots strikes me as unethical. The extra bridge officer slots makes for a better away team makeup, as you can have multiple of the same type (this mission has a lot of enemies, so take 1 science officer and 3 tacticals or 4 engineers for the aoes, or four science officers for super heals.) They may not be game breaking, but they are game altering.
