As @Laz Manpointed out in a necroed thread from Summer of 2020, it is pretty interesting to go back and read about the changes that people struggled with and how those things are just non-issues now because we have adapted and learned. At the start of every alpha there will be people who rant that their playstyle or base type or x is impossible now thanks to the changes-- but then months later nobody thinks those things are impossible any longer because-- learning happens. On a side note, it is also interesting to read posts from people who haven't played in a year or more and then they pick it up and they have the same learning curve issues the rest of us had a year ago but they are just posting about it now....lol.
So, just wait for all the angry posts from people who will not know how to play Alpha 20.
