talking about the new type of events in PvZ2

the events in PvZ2 have changed a lot and I'm here to give my feedback on the changes
the event shop:
Now you can only buy more energy with gems (no coins or ads) not only that but you can only buy more energy once (and it takes 8 hours to earn more)
Hard Mode:
Hard mode isn't really difficult and not only that but you only have hard mode for the second half of the event.
more experienced players should have some fun too.
event tokens:
It would be nice to be able to trade tokens for coins and gems too, even if it's more expensive.
replay levels:
replay levels should be free, pay 20 energy for this it's not worth it considering that now energy is very expensive.
