Let's all acknowledge that sooner or later inflation would destroy the economy and would make the game unplayable for all legit players. Just 24 hours after the siege, the accumulated tax in Giran was around 120m. If I am not wrong, when the tax rate is set at 0%, the tax revenue comes only from a percentage (10% at most) of the sales to npc merchants. Meaning, that over a billion adenas was made just by selling crap to stores. If Giran has 500 active players (lol), this means 2m per player, per day.
However, this update really destroys any chance for a new player to catch up. Sure crafting and buying C grade and B grade will become much easier and cheaper. But with adena drops as a sole source of income for new players, everything will be unreachable, even at low prices. The only alternative given by NC West to new players is the high grade starter pack in l2 store. As if they are saying "New player? Great! Look at this amazing offer we have for just 5 dollars! Don't want to pay? GTFO!". Of course this is a p2w game, of course you will eventually have to pay if you want to play for more than a month. But this will make people to quit after their free duals expire.
Give players alternatives to earn adena. With quests with dialogues with npc that needs logic that cannot be automated, maybe better untradeable rewards at 40 lvl dungeons.
As more and more quit, without new players this game will die. What makes me uncomfortable is that the new update is not fair for the new legit players and the providers make nothing to change this. And the worst part is that this seems deliberate and calculated.
