There two buildings that’s unlocks stuff but doesn’t unlock a unit.
Lair and twilight council and i feel cut them out all to gather it open more options.
Remove lair you add old upgrades that was removed because it was put behind lair.
Now Protoss would be more vulnerable from faster drops but if u remove twilight council and place upgrades in cyber core.
Then after cyber core you can replace twilight council just with Templar archive.
I would remove queen nerf can’t transfuse off creep.
So what would game look like Zerg can protect its self from proxies because drop creep quickly. You can go offensive but it won’t be good as cannon rush unlike cannon it be very easily spotted.
By time bring queens over Protoss would have feed back that hard counters queens. They also get faster blink and speed zealots.
I do think one change for Protoss since with no lair even if it’s locked be hind an upgrade faster overseer. Terran has scan I feel observer should be made in nexus add it unlocked with cyber core.
