I think the game needs a little more PVE content but with party system. Yeah alt content is fun and weekly guild boss rush but having some sort of party system to run dungeons with mobs and bosses would be fun. Now it seems we are all farming for pvp endgame stuff. Solo play is fun at times but adding some feature like that with daily entries and having rank rewards at end of week or month for teams or players with highest dps, kills or speed runs would be fun. This would widen whats offered and not worried about getting high CP killed in BOTS or Black Sun etc lol. Giving not everyday players some action on other things not just PVP PVP oh and PVP. 

There is more than enough pve content in the game. Desert, ocean, merchantry rift/hadum/nightmare/chaos rift, world bosses, guild events, boss rushes. and im sure im missing out some. In most games the endgame content is pvp focused. You usually do pve to get strong enough to do pvp. I do agree with a more organized party system though. I fail to understand why some games dont implement this feature. The party system they have now is some kind of que where players are chosen randomly. Which is ok but I do think adding an "invite to party" system would really make this alot more interesting.
