As a new player that returned after a long time i was very disappointed with how the updates not only generalized a of of the good and uniqueness lineage 2 used to have but made it almost boring.
Quests that send you over and over to kill 40k monsters for 5-6 times aren't fun, rewards are none existent, a low level character or anyone new in the game have virtually no way to make money to survive beside s praying 2-3 boxes they get from dailies give them something. There is a lot of useless downtime on leveling at certain levels ( 105-107) which make it almost impossible to find groups and so on.
You cannot have zones that are advertised as level 102 only to have the lvl 105 get 2 shot by the monsters there, its insanely unbalanced.
Allow players to make some kind of money or to spoil/drop stuff and try to get the economy back on feet, right now the economy is terrible.
Try to overhaul your vitality system at the moment it feels extremely redcurrant unless you're forced to use some specific store items.
Make your prestige subscription more lucrative and not only about boosts.
I can go on for hours on how the game is getting almost unplayable at this point and how both pve hunting is a joke, world bosses need to have a variety for lower players as well.
As for pvp , sometimes but very rarely can be fun but current situation watch Aden sieges having max 20 people fighting against eachother because others know they stand zero chance against " stacked" players makes it a joke. revamp the pvp, still give whales some advantage but tonne it down especially the dmg multipliers
