How do we know how many new players join the game? If they are trying out the game as free-to-play, they can't communicate in map chat, and chat is quite limited overall. You'd have to see their toons in the starter zones. And I do see some, but have no way to quantify them.
The forums certainly don't represent the game population. I'm the only one in my family (5 people playing) that frequents the forums. That's just anecdotal, but I think a good representation of forum users. How many just lurk and never post?
Not that the game is without issues. @"Astralporing.1957" did a good job laying out some problems. But you know what? My brother and daughter are the most recent in my family to join, and they are blissfully unaware of any of those points. I told my daughter a new living world chapter is coming out next week, and she said, "A what?" All the stuff discussed here has zero affect on new players, unless they are perhaps MMO-jumpers and spend a ton of time reading up before jumping into a game. My family will be playing a long time before any of those "issues" come to light, thus making them non-issues to them.
