It's not that bad.
After the past 4 events before this one, it was worser.
And maybe they give away to many things and XP, so people dont have to play a few hundred hour to get 1 country full 120.
It's more like set a ammount off sailors at lvl 75, and you can easy grind them up to lvl 120 in a event month.
So if you play only event and a little more in front to prepare your sailors for upcomming event, it will be pretty easy to get 3 or 4 full sailor ships to lvl 120 in a year.
So why would you play more.
My first bb6 take 1.5 year to get all full 120.
Now i do 1 month and with event about 2 week. ( between 40/100 hour gameplay)
So only the people who like the game, play when there is no event.
