So from what I'm gathering, the point of the original post is to say that if someone comes on here and says "X sucks and shouldn't be in the game"... it is a waste of time for someone else to come into the thread and say "Well, then just don't use X."
If I'm misinterpreting the point, please correct me.
But assuming I'm on point, there are really two different aspects of this that require discussion. The first is when the game already includes X, the second is when the game does not yet have X in it and there's still a possibility that the D&D staff could be convinced NOT to include it in the future.
As far as the latter is concerned... that kind of discussion is understandable. You don't want X in the game and there's a chance it still might not be? Sure, there's a discussion there. Hopefully the discussion's argument will actually be about concrete reasons why X might be a good or bad idea, and NOT just "Add X just because!" There's no reason to add things to the game "just because" some people might want it, and WotC has proven over the last 3 years that they AREN'T going to add things "just because" people demand it. So if there are pros and cons to whether X should be in the game... threads talking about the pros and cons are good.
But in terms of the former... when X is already in D&D... there is absolutely NO REASON NOT TO have people come into the thread and say "Well, then just don't use X." Because there's no discussion otherwise. The game DOES include X. It is IN the game. And it is NOT being removed. Not in future printings, not via errata, not in any other form or fashion.
As a result, the fact the thread gets created is itself a pointless waste of time. What exactly is the point of a thread where the originator states "X is stupid shouldn't be in the game!"? When there's absolutely no way to change it? To me, it is merely a "Hey look at me!!!" thread where the person has this compulsive need to tell other people what they don't like.
Which is fine, I guess. I mean, if you really have this uncontrollable urge to tell others your own personal dislikes on a message board such as this, that's you prerogative. But if you actually are going to CREATE such a thread... a thread that exists for no other reason for you to rant about what you don't like... then there's absolutely no reason to think you SHOULDN'T receive responses that are essentially telling you to stop being a big whiny baby. Because again... your thread serves no practical purpose. X exists. It's IN the game. And since there's nothing for anyone TO ADD to your thread other than just a bunch of 'A-YUP's! from other people who agree with you... what else are everyone going to say other than stop being a big whiny baby and just not use X.
And if you don't WANT to essentially be told that you're being a big whiny baby... then don't create a thread where you're trying to deny reality. You don't HAVE to create a pointless thread like this. Just like we don't HAVE to stay out the thread pointing out how pointless it is.
Is us coming into the thread "helpful"? Of course not. But then again... the thread has absolutely nothing to be helped with in the first place.
