The wm survey Q1 is for realm type. It only matters in wm if they are on rp or normal wm shards.
Both wm survey and wm forum are a small section of wm players. We can take these two sources of limited information, and get an approximation of what the overall wm playerbase thinks of wm.
Wm forum and survey are quite different as info collection methods. The wm forum is semi anonymous, tends to be strong opinions, sometimes enforced with bullying. The wm survey is fully anonymous, players can state opinions without being called names or told to stop posting. But still one is not necessarily more right than the other.
Their info combined, you get a better approximation of overall wm opinion, than just going by wm forum posts alone.
Therefore, if I reply to a wm forum post that is limited observational info, seems reasonable to respond with a limited info survey. Anyone scrolling down the thread, can see both sources of information in one place.
That will never happen. All we have is limited info that we can use as a guide, wm forum and wm survey.
