For start i want to say that l2essence is very exciting till now but some new ideas for making the game even better isnt wrong to porpose. I want to suggest to developers to increase the number of mobs in the island so that i can exp there and join a pvp clan. I believe this would encourage more pvp ingame as many people like me would join pvp clans full of wars. Also you must put a pvp reward system that rewards players at the end of each month. Also olympiad rewards should be better , so that more players would join oly.
Problem with oly and other rewards is, that any items which they put in and for oly points will decrease their sales profit from l2 store and lcoin...so u got the answer regarding this topic
