Well your original post looks more like a rant. What do you expect from people to say - to agree that it's hard to get free frags for free, which we all can agree?

If you want to stop paying for events, that's fine but there sadly, a few who will continue and that's what Oasis cares about. If you see people with multiple 4* (like 3+), more likely they are whales but it depends on the server since an older server, you are more likely to build 4* via the coupons you have stockpiled in comparison to new servers. Just look at the meta and do you research as to what ninjas you would want. Most people do 4* only for the breaktrhoughs besides the whales who are willing to spend.
