Thor's are half worthless as it is. 20% damage increase to massive means jack and shit. Thor ground range for a Thor is 7 where Colossus with Thermal Lance is 9. Plus with that minor (and useless) buff Terran is still getting nerfed again with repair. VR's will just own a Thor post patch because Thor AA is pretty piss poor in reality.
Tanks half-assed? Check.
Depot before Rax? Check.
Reapers the most worthless unit in the game? Check.
Can't repair BC/Tanks/Thor/Barracks to make them cost effective? Check.
At this rate it may be time to switch to Protoss...
You aren't a very good player then. PvT is almost completely balanced as it is. Toss just has a disadvantage early game, but mid/late game they're pretty much even.. Just stop using tier 1 units when you're in your late game noob.
The only race protoss is more imba against is Zerg with the colossi. Other than that terran is the most imba race imo.. If you wanted to climb up the ladder as high as you can, then you might as well play terran unless you're pro.
