I don't think they want to destroy the server with bad ideas, but they fail to think who plays L2 today.
Lineage is an old game, and the vast majority have limited time to play (study, work, family).
We're faithful to the game, but why make us suffer if we want to enjoy?
Generic macro and too basic (or not tested).
Spoil mobs Lv70 for craft items B grade ?.
Fish not tradeable?.
Few opportunities to do pvp (no fortress, no nice sieges).
Red Libra event very limited at classic servers.
Quests with insignificant rewards.
And the list could go on!!
