Hmm, on this server here basically anyone can play any class and no matter what will always find some people to level up with. Sometimes it takes a little while of finding those, but at the end it worked out well for everyone I know. This is one of the very! positive aspects on this server. You will notice the difference between playing here and at EU.
It's mostly like this: What class you play isn't important as long as you are friendly, helpful and do your best in playing your specific class.
I for example had no problem at all to do PVE with a Dragoon, or with one in a complete party. Actually I have done so multiple times in game now.
Sorry I can't say anything to the PVP aspect on here around about any class. I'm just and only doing PVE.
But I believe since the nerf this class is okay being "wanted" in PVP too - but like I said, I have personally nothing to do with PVP at all.
Being in any guild is a very positive game experience for many on here too. Just a thought.
