I myslef like replying to people , and there was a recent thread where somebody asked something about Pythium vs Ermor fight. I thought of an answer(from my logic and understanding) and I wanted to reply, but I didn't because I was not sure if that is the actual answer and didnt want to confuse the guy that was asking. And while its true that sometimes people correct you, sometimes people don't know what they are talking about and still post, which leads to misleading information and doen't help the game.
Imagine you used some misleading advice in one of your games leading to you loosing a battle badly(which you should have won) and eventually to a slow and painful death in that game.It will leave you with a very sour feeling, as these forums are supposed to support the game and not ruin it. Any misleading posts should be avoided since they can ruin the fun for many players(remember that one mistake(by being misled on the forums) you made ruins a whole game which you have been playing for a long time thus depriving you from your fun you would have had if someone didn't post the misleading info).
Testing one of the things you are talking about it not as life consuming as you say. It takes 2-3 minutes at most(especially if you have already set up a game saves for tasting with the debug mod). And its quite educational game-wise since the guy that tested it can afterwards use it in a game.
Also If you were speaking from memory as you said its nothing wrong about it. But some poeple don't(quite a few newer players) they just presume that things must be so and so and state presumptions as if they were truth. And that as I mentioned earlier doesn't benefit anyone.
So that was why I think you got such a sharp answer from Calahan. But he is actually a really nice guy and he is just trying to benefit the whole community by answering you like that, so don't take it personally
.
P.s(just writing this post was way more life consuming than testing what the guy was initally asking about)
