The point that you clearly missed, was that adding a bit of action to RE7 doesn't mean that action RE fans "are still being well catered", since the action portion of RE7 plays nothing like RE4-6. And it's very typical of most horror fans to try and silence action fans of the series, without actually understanding what they want, just like how it's happening in this thread with the "take this action DLC and don't whine anymore" attitude.
Also no, RE6 fans are not feeling betrayed. On the contrary, it seems like horror fans can't get through a single RE thread without bashing and hating on action RE, which results in RE4-6 fans defending the games that they like.
When it comes to RE7, I'm not its biggest fan but I did enjoy the game enough to be okay with the future mainline entries continuing in this style. What I (and many other action RE fans) want, is to have a TPS action based sub-series alongside it, so we can enjoy that style of gameplay as well. But many horror purists see this as an absolute heresy that shouldn't even be thought about, which makes most of the RE threads unbearable.
