The higher rates on Nutaku dont really concern me, since I decided to not spend on Nutaku anymore (unless its something like another black friday deal or similar).
Also - the thing, the one love and hate feeling each of us have with these Gacha games is exactly that > Gacha.
It will piss you off hundred times, but then when that one times you finally strike Gold (Rainbow in this case) you will cherish it much more than if you shelved out money and just bought it like a loaf of bread in the 24/7 store. :P
Also I really want this event to be gone already, currently I have nothing to do in the game honestly. Farming whaleship is pointless since I dont have anyone to equip that powerful equipment onto since my 6* lack the inventory slots, and my 5* with all slots usually have their own event equipment. Only Nadeshiko has 3 slots opened from dupe roles, but she still needs one more if she ever should get the WS equip.
Dont really care about the perma re-issue events, and cant even do manyus since I mass upgraded a bunch of girls and now I am short on gold
So yeah kinda stuck waiting for the new event and just doing the "Mirror Fights" to get some equipment evolution stones in the meantime.
