The way the game and XP mechanics go, this game has unhealthy system.
The way the skills work right now and skills are acquired are meh.
And nothing is in the game besides grinding, grinding, grinding, and leveling up and again dungeon. For hardcore and grinders this game is a total heaven.
1st rate spearman, swordman and bowman/archer will stand on the top of the food chain.
2nd rate citizen would be magician and support. Lower level mage and support would just be disappear.
When PVP will be available, staff and wand users would be the lowest class IF on the same footing, without any intrics (I can guarantee that).
The highest level will help lower level only to gain money to enhance their equipments more (get all main and support weapons to+100), crafting/finding the best magatamas, clearing dungeons, and collecting dropboxes.
When all the higher levels are already bored with the game, they will leave and only log in once in a while
Most support would be VIT/MIND or POW/MIND or DEX/MIND. The true support (MIND) will disappear along with the resurrection.
The rest that come to this game will be the occasional highest/higher level player, and some/few casual player that has gained some levels, and very few lower levels.
Notes : Kinshiden and Byakkou will still flourish since higher level needs the drops (magatama ingredients and some rare ingredients).
Once all the community dies out, the server will close down along with community. Or becomes ghost towns.
