I noticed that after a big expansion we have a lot of buffs and nerfs (April-August-December); after a few weeks we have more with the battle update and they are smaller (May-September-January); after a miniset we only have nerfs (june-october-february).
I would like to know if this sequence was repeated even before 2021. I started playing at the end of 2021 and I don’t know the previous update dynamics.
