Glad to hear the beta is going well. Looking forward to when it comes out on android.
For me a grind is fine. I'm just worried about say a year after release. There's been games I've tried a year after they released and when you start they bombard you with so many bonuses that the game, especially the early levels, feel like a joke. I just want to play a game not go "Oh yay another bonus thing."
Slow drip on the Belles is fine for me. I know when I tried Azur, shortly after playing for a bit I had sooo many ships that it was a joke. They stopped feeling special. As long as I can grind for the ship that I want, I'm good. For example: If I want to earn Vestures for a particular ship then I should do X, Y and Z level, or something like that.
