A big list of changes. There are quite a few buffs to support a Mech or teching based Terran while increasing the reactor time and reducing SCV HP to balance off the deadly Terran SCV Marine all in build. Protoss got another downgrade while minorly boosting the Stalker. This makes Terran Bio vs Protoss Collossus a lot stronger and survivable. Zerg got the downgrade for roach regeneration is probably due to the Zerg vs Zerg matchup and Protoss vs Zerg matchup where they can really cause great damage and difficult to be countered in the early game. Other than that, the other fixes are good especially the pathing system where games are won or lost by the ramp. We will definitely see more Mech Terrans soon enough.
