It's a lot easier to get lots of heirlooms now; I started hitting level 60 a few days ago and I already have 38 of those, giving me +1.14 flesh/s. It's really pretty good and grows decently fast.
i enjoy the game over all just i feel its a bit to slow in gains at times
like why not have the flesh heirloom be .1
as it just makes a prestige take longer to recover from as is
and why have cards be so random i can never pull anything good for duplicates or complete any sets ive spent 100s of green gems on them and still keep failing to get anything worth it
