Fixes:
Make adena/experience balanced through all hunts zones. What is the point of various hunting zones if only one or two are worth adena and time.
Remove auto-bot
Remove bots (all of them)
GM buff and events on weekends
Disable this "box" practices and make every class self sustainable just like any othe mmo. You can think of many ways to achiev that. I know the essence of L2 is people playing together but people don't to it... people just have 6 accounts running (Virtual Machine) at the same time <-This is weird.
Modify and improve how boss loot work stopping the monopoly
Profit (L2 Store):
Add set/weapon costumes.
Add extended character costumization tickets.
Add mounts.
Instead of lootboxes with pay to win items, add lootboxes with rare seasonal costumes and mounts (halloween, xmas, carnival...etc).
Put the recent "teleport anywhere feature" to the VIP only accounts
Radical changes (CEO approval):
Add 3 servers: [1] North America, [2] Latin America (spanish speaking only), [3] Brazil; or just 2 servers merging Spanish and Portuguese together.
Add IP Block feature just like Vindictus has so people can't invade other servers.
Remove item break upon fail enchant. Just revert the item to +0 upon failing. In compensation, make it harder to enchant lowering success chance percentage. Maybe add a L2 Store item that increase the % chance slightly (like +5%).
With a brainstorm discussion many other things can be done to keep l2 health and profitable at the same time.
