SC2 5.0.16 PTR reshapes early economy and gateway strategy

Blizzard’s StarCraft II 5.0.16 PTR patch broadens 1–3 base viability by overhauling the economy (bigger mineral and gas pools, updated per-base resources) and shifting Warpgate integration to the Gateway to enable non-warped Gateway play, while delivering wide balance tweaks across Terran, Zerg, and Protoss plus extensive QoL and bug fixes. The goal is to extend the early/mid-game and encourage more diverse strategies with improved visuals and UI feedback.
