This week's patch is a bit more laid back. It's a smaller change but still (surprisingly) gives a small boost to the Terrans and another small nerf to the Protoss in the form of a 10 HP reduction in the unit's shields. The Terran received across the board reductions in the upgrade times for its infantry and vehicle and ship upgrades (all the upgrade times were reduced by 30 seconds). This is a significant boost since in StarCraft 2 a +1 attack upgrade gives a +5 attack bonus. That means +2 would give every unit affected a +10 damage boost.

There are also some bug fixes including a correction to Reaper pathing.

oh noes not my zealot! this your lucky day jon.

Good to see they are doing these small changes to the Terran. I don't see nearly enough of them, and even less with any upgrades.

Can't wait to try this out.

wow lets just make the protoss completely useless. like pro players are going to completely destroy players with terran now!

I've seen taht the reapers and the motherships have decreased their power, and they cost more and take more time to be built. Like it is said that they are useless.

What happened to the radar tower and the sensor tower ? Have they been cut ?

No no. This is not a nerf the Protoss patch. This is more a how would games be affected if we nerfed the Protoss. Since most balancing is trial and error I think these patches are just Blizzard's idea of trial and error. And you testers (yes testers and not just lazy players) will be testing out these ideas blizzard has for balancing.

heck make me a tester and give me a beta key!

Sensor Tower exists ?

I hope they make some changes to the Zerg soon.

Wish they did some zerg changes, seems like all zerg players do in vids/streams is mass roaches. I rarely see any broodlords, or any other high tech zerg units
