EPTDoesn't add any value, just detracts.
The random decision to power creep zerg's larva was one of the most asinine things I've ever read, especially with no additional changes (aside from a queen cost revert which is even more ludicrous in conjunction).
Doesn't fall into the realm of oversight, it's just utter incompetence.
I think gateway build times post research has been an interesting experiment (current construction times are quite wild with how quick they are), but then on the other hand we've landed on a triple nerf to warpgate is most cases... The base research increase, cost resource per gateway, every unit except for stalker and sentry actually has a 2-3second longer cooldown.
If this is the chosen path it makes more sense to just axe the idea of warp-ins altogether. Myself and others have given several alternatives that create a much more cohesive experience.
