Hi again,
thank you for your reply. If you are willing to update the guide regularly in terms of changing class balance then sure, you're absolute right and I'm completely with you on that matter. I honestly haven't considered that there is actually a large portion of the player game that adapts a "fotm" style of class preference.
I also can't exactly speak for all the servers for obvious reasons, but there are still quite some players around which you can group up with. Mystiel is probably the largest of them all (which doesn't say much in the first place since the game itself isn't extremely popular anymore) but it's probably better for newcomers to be open about this, that you'd personally recommend Mystiel due to higher player count, but not force anyone onto that server.
Anyway thanks again for your time. Just don't think that I have only negative thoughts about your guide as it's pretty great overall except for these miniscule things.
