Is a new balance possible?

I just returned to SC after more than a decade and something I saw immediately is that my race (zerg) have suffered some changes like the spawning pool price which went from 150, like all other races, to 200 minerals and the consume skill on defiler that I remember used to be free now requires investigation.
Something that I have seen playing lately is that zerg loses so many drones while trying to create buildings, in fact is the only one with this disadvantage, which makes it way harder to expand and create defenses like the other races and plus this puts a toll on all the mining. Do you think it is possible this game could get another balance?
