Thoughts about the current Meta

Based on my experience against final boss Flare Volg:
Brawler is a really fun class to play but it lacks of synergy with others in group. A typical agi brawler is good at soloing but soloing takes forever and it cannot solo silver roar.
Healer support class. Dont think we need them at all for now. Having a healer in a 4 men team actually slows down the battle a lot.
Mage: water mage is pretty much the most wanted class right now. Pure damage dealer to the dragon.
Archer: not very hot right now. Dont have any good weapon like the other 2 DPS classes.
1/2H Warrior: same position like archer, always second place in DPS if there is a water mage in the group.
Tank: Usually needed if you have like 2 mages in your team or people are too lazy to run around, otherwise it is possible to just kite the boss.
