First who am i ? i’m a player 
I played 50k+ hours mmorpg. I know what a player wants. we want equality and balance (because real world is not equal. ) but that’s against the logic of a mmorpg. Everybody wants equality but we play to win. (very ironic. there is no equality if there is a winner) Now let’s come to my suggestions:
-Merge empty servers.
-Open new servers for players who complain about bugs and dupe.
-If u r systems not good enough for 50v50, break it up into stages. (game engine, servers or bla bla… )
-Give the opportunity to join the corruption for solo or hardcore players.(Hurry up for this 
)
-Fight with macro and cheat. 1k banned for dupe. items and coins. Not enough. Economy and
hype train broken. (amazon was so soft )
-DONT create complex game mods. Create simple game modes that are easy to control for developers. e.g :
Create empty beach. (let’s call it Zone) What are the rules in the zone ? Zone must hide player names and give standard items. Players cant enter with own items. Create simple design, big empty beach and ships. Target is to collect locked chests from sunken ships. Take it and carry to the NPC. Npc opens boxes for you. the way back is purely pvp There should be a daily limit but must be accumulated. So players don’t fall behind in the process. players can complete them all on weekends and holidays
- Cor. Invansions system really bad. Whoever thought of this please don’t do it again
