Or just stop playing. Starting anew is a meh-y idea at least for me. And lets be honest - I play this game to get mah wifus and their h-scenes. Battles I just auto/afk to not see fails on RNG and thus not to not get angry.
Also its Nutaku. They probably give zero fucks about F2P players. As long as 'whales' wont whine that events are 'imposibru' to do even with dropping bunch of FGs, then nothing will be changed. Thou I wonder - last gacha event was so broken that you could finish it in phase one doing full clears on all resets supposedly as an apology for late start or something, but when this event started we got like 5 FGs as an apology for this event being late IIRC. So seems they learned their lesson and instead of making things easier, they just gave few FG to refill stamina to "get back" lost time.
