Just point out that what the majority wants is not always the best, and in theory the class with the most players could nerf down all other classes to shit and then keep on dominating the servers.
Or, the house of EU is a lot bigger than the house of NA, and whenever a suggestion might pop up that's against EU for the better of NA for an example, get's downvoted to shit.
(This was only an example for a situation, don't start nitpicking over it.)
This happens in my country right now, that dumbass clown got in with like 75% politicians of his own and now abuses it like crazy, giving us a bad name in the EU. Sorry for offtopic, but I have an IRL example for this.
Also, giving someone decision making positions just because he did something, or is "veteran", is the dumbest idea I ever heard. Just because one is a veteran, seen more things, that doesn't automatically mean that he can do a particular role well.
