There are many things that need to be improved and others that have been left aside and not much benefit has been obtained:
SW: Despite the efforts they have made to include PvP on the server, it has been of little or no use. It's still a PvE server. There is still a need for further improvement in this regard, improving the loot of war that is somewhat attractive and updating the map.
Do quests and go to old lv 90+ maps. To obtain any benefit and entertain yourself is completely null. As well as the updated nostalgia instances, where average players and not just end game can run, to get something that really benefits.
The latest nostalgia instance updates are aimed at pro-players only. Many new and average players who do not have the best equipment can only aspire to run the same as always, tikal, inferno, etc. That really discourages those who want to move on and run something different.
You have to work a lot on class balance, there is a lot of disadvantage of magic vs. physical classes. With chainmail gear there are 2 or 3 dps combinations that are viable, while in magical, there are many combinations that really work without having to switch weapons.
Despite being an old game, it can be very attractive to involve new players. But they have stopped investing in advertising. I started playing this game a little over 1 year ago because of an advertisement that came out on Facebook that caught my attention and I decided to enter. Said advertising has apparently disappeared. To keep a game like this active, new players are needed to join this adventure.
Usually most of the players are from the US. Therefore, the schedule of greatest activity of the game is proposed by the schedule of the people of the US. Attracting American players would be an excellent plus so that the server is active at most possible times, and that it is not dead at certain hours as is currently the case.
