Interesting thread, in my opinion Oasis just needed to add a couple more f2p events honestly.
The ratio of events is just way too skewed towards p2w, so how could they not expect the backlash from the rest of the player base which is a huge majority.
What rewards i would like from anniversary:
1. Any free ninja from daily login rewards similar to Myobuku trial (We may still get free ninja from login rewards but i highly doubt so)
2. Anniversary clothing with 0 stat increase and just cosmetic purpose (it's the thought that counts).
3. Maybe throw in limited recruitment event where we may get 1 limited point for clearing instances which synergize with ramen event.
