Without f2p this game would not have the player base to work. It's a balanced ecosystem where everyone needs everyone. If you suddenly change your release strategy for these big events and drive away your f2p base then the game will die.
Double drops have always preceded big events to help us on our way. It's a way of rewarding loyal players that login every day. Combining the hardest ever panic farm with no help is a big f u in my eyes regardless of how much you are willing to spend
