I'm just going to say this. It doesn't matter if they gave out free Rt every month whether you have the UC for it or not, the fact remains that there is still a huge division between free players and cash players simply by the amount of content which is PURE cash and the amount of content which is UC yet can still be purchased by cash. This is absolutely NO semblance of balance. The ONLY instance where such a system works is when all content that is pure cash is purely cosmetic OR minor convenience.
Furthermore, the argument of them making garapon easier to get is about as valid of an argument as the lottery taking one number choice off. It does not strike balance between free users and cash users. It does not strike balance between free content and cash content. It does not make free users any more at convenience than cash users. It is at the benefit of the CASH USERS that rare items are easier to obtain in a CASH CONTENT.
And before the argument of in-game currency to cash, i.e., UC -> Rt comes out, it is a five times a month feature which boasts an incredible amount of in-game currency to use, and gives you enough cash for the most minimal of things. It is not a light of salvation for all free users, it is the royal castle's sewage that you have to fight to the death for.
