we are now entering the center of "complain" phase

[Melorie]

Lets get real here. Some of these people who are "discussing" their classes are saying little other than "MY CLASS IS RUINED!" I believe it is these sorts of people OP is on about. There is quite a bit of headless chicken panic going on among some players.

Yeah of course. You'll have people writing texts and texts about the changes and you'll have people that will just scream AAA MY CLASS IS RUINED, not every feedback is elaborated. Because that's part of the process of dealing with new changes, specially if those changes are impactful or big.
These people will ALWAYS exist. Making a thread talking about them is pointless, even more pointless than a person talking about what they think about the class change in a dramatic way.

You're browsing the main sources of discussion of the game (reddit and forums) after they released the infos about the classes on the expac... I mean seriously, what do you expect? Even if the changes were amazing they wouldn't please everybody anyway and there would still be discussion about this, which is not bad. It's normal.
If you want everyone to act a certain way, just talk about it with close friends of yours that probably agree with you or are deal with things the same way you do when talking about stuff. Do not go into a place full of different people with different mindsets and tell them "you're making me feel bad!!". I mean, c'mon.
