Yeah, it's a double edged sword. But most of the time it's better to speak out if you feel a character is broken or shit sooner than later. Because once a set amount of time passes and there is no more patching, that character will forever remain broken or shit. I think it's better if you have someone say "Hey, Mileena is broken" earlier in the game because developers will have more time to invest into that theory before their due date for an opportunity patch arrives. Rather than have people wait and say "Hey, Mileena is broken" two weeks before a due date for a patch is set because then developers may panic and create an unnecessary last minute change due to fear. I feel like the whole Scorpion scare was victim of everyone overreacting at the worst time possible. (The DLC patch and EVO were right around the corner when it happened).
