Sage has to make money some how community. This is the 1st rollout of the New mission pass. Sega 1st goal is to make a great if not Epic game and their 2nd goal is to turn F2P players into paying customers. They have to make money to create content, they have to feed their families too. Us as a community have to get out of that mentality of something for nothing concept.
Sega also has to get out of that mentality of getting something for nothing concept. They haven't given us any real content besides 2 new classes and 2 sub par 'events' that were nearly 100% identical to each other. Even with 2 new classes, there's nowhere new to explore, no new monsters to battle, nothing new to do in the game. It's the same endgame as the original classes, just with some different Photon Arts to use. I haven't really seen a reason to spend money in this game given what's been done with it so far.
If they want to make money, they have to create content that players want to play in a game players want to spend their happy gaming time playing.
