You can very well scream at the wall, effect will be the same. Oasis is hopelessly blinded by money, they believe only whales matter and only whales deserve anything good in this game. You want to change it? Stop playing. If every single f2p drops from game, whales will follow as they will quickly get bored by fighting mirror matches where only Initiative matters. Then, and only then, Oasis will realize what they have done to this game. Nothing else will work, you will either get ignored or hear "bro, it was always pay 2 win, just deal with it"

F2P events used to be good. Not great, maybe with exception of Fuku, but you could get meta ninjas from them within reasonable time frame. Then Infinite illusion appeared and players could get big amount of coupons relatively quickly (I did some math back then, you could complete 35k Fuku every three, maybe four, months if you were in top 20 in each illusion trial) and, surprise, quality of events dropped like flies. Now even Fuku is bad, unless you save 110k and even then it is not guarantee you get meta ninja.

If you are f2p and do not play to keep in touch with some other players, there is nothing on horizon that will make game better for you. You should rather expect the opposite.
