Character Shards
After each era, we have six characters ranging from 3-5* (I know there are more). It's impossible to level up Clay Marco (or any character from this era) to 7* in two weeks with energy, even if I retry. Also, the era's assault battles don't yield enough shards to level up all six characters to 7* in three months. Also, getting a 4-star character from this era only gives two R6 tokens (a 5-star character only gives three R6 tokens).
It's time to revise the shard drop rate for f2p players. Otherwise, after each era, we'll have an increasing number of unleveled characters, and the frequency of obtaining characters from the Guide will only increase until several years after their release.
Increase the number of tokens received from 5 for 4-star and 5-star characters (2 and 3, respectively) to 7-9. Also, increase the shard drop rate for all characters. Otherwise, the 1-2 shards we get every 10 battles will take us too long to level up to 7*. And we'll also need energy to level up from G12 to G13.
