What if… Observers were built from the Nexus when Protoss gets to Robo tech? It would be more in line with Zerg and Terran coming from their main structures. Would make scouting and vision easier for Protoss. Would not overlap with Immortal build time on the Robo.
This is interesting because despite the buff to robo, it's a slight nerf to Protoss economy, perhaps an increase in build time as well? That could help the TvP economy meme
