What does gatcha's and black Fridays sales have anything to do with people not liking the new combat voices? Heck I haven't heard any say they are stopping playing, let alone stopping paying Nexon money. At most we have said we just play without the sound, and are unhappy because of it.
Devcat and Nexon count dollar bills, not long-winded tirades on a forum or edgy one-liners on discord. Nexon doesn’t need to care about you liking or not liking the new voices as long as the cash keeps flowing in.
But you wouldn't get it. You're one of those people.
Constructive criticism can be great, but I got to say that it seems to me that there are a lot of people who are the type who just want to complain, or jump to conclusions, or have such a negative view of Nexon that no matter what Nexon does, even if they do everything perfectly they'll always hate on Nexon and say they're doing certain things when they're literally doing the opposite, or they'll just jump on every small little mistake in such an over-reactive manner due to their unchanging hate of Nexon.
Like you said, your view of Nexon will never change no matter what. Do you not see potential problems with that way of thinking? And I think it's safe to say that there are different types of people with different types of tastes, so there are people who genuinely like things that you don't like. Like the recent voice actor patch, I like it or at the very least I don't think it's that bad, and it's possible that the people who hired the voice actors picked from a line of voice actors and just thought these VA's were the perfect fit.
The missing patch notes are a problem, but it's hard to be completely on the side of people who only complain and hate and assume when everything isn't going perfectly their way... heck I have my doubts they really know what exactly what they would want when it comes down to the details if they actually thought about it.
