No and no.
- The game mode was added to be a casual and fun game mode. People grind because they want the floofs. It was never intended to be such, although it is an option. Not everyone has the time nor willpower to sit in a chair all day playing a redundant gamemode to get a just few cosmetic items.
- That contradicts your first point. If you are saying that it should be a grind, then in no way is rewarding better play the same as lowering the prices all together.
To clarify, I think the event is cool, and I am in no way complaining about the game mode itself. DE doesn't owe it to us to make this, however there are some issues with the co-op aspect as far as the kill-stealing which is now a problem and a motive for toxic players to jump into.
