The trend towards making buffs time-limited rather than items you can keep is annoying. What is even worse is what the time-limited buff decision confirms; PA has balanced game progression around people treating the game as a job. Income is measured in billions of silver per hour, while reaching endgame goals requires trillions of silver. This system is demotivating for players; while there has been renewed player enthusiasm for Olvia Academy, that will likely only hold until these players reach the demoralizing endgame. Players who spent thousands of hours playing the game and "ran out of things to do" complained to PA about this, and we all got super slow progression. In most games, people who spend hundreds or thousands of hours playing the game accept that they have "run out of things to do" and don't blame the game for that; why should BDO be the exception? By slowing the pace of progression, PA may have won the support/engagement of the super-hardcore player, but at the expense of turning away everyone else.

Didin't they say a not too long while ago that they are removing time expiration from event buffs? I remember that! 

Expiring event buffs do not motivate to grind/lifeskill more than you are doing already. The only thing I think when I see the "will be deleted" is "Fxxx you".

Yes, one of the buffs that PA removed the time expiration from was the Ode to Heroes of Yore buff that drops from field bosses. Removing time expiration from this buff has helped motivate people to run field bosses. I don't get why they are reintroducing time expiration, it's not a productive direction to go in.
