Just watched the third battle report. Looks good so far, but I think it was clear the game was very lopsided. The only reason it even went on as long as it did is because all of these videos are intended to show off some back-and-forth with different units and tech.
I was always a Zerg player primarily so I am happy that it seems like the Zerg have some actual variety in units now. I am so sick of Starcraft 1 where half the Zerg units are useless (Queen, Guardian, Devourer, Ultralisk*) and the only good spells Zerg ever got were Dark Swarm and Plague -- Both stacked on an easy to kill T3 unit.
* Ultralisk is used in pro level play but all it ever does is soak up damage. 4 Marines + Medic can probably take down one Ultralisk, not exactly impressive for a T3 unit that expensive.
Anyway, the Protoss look way overpowered compared to Zerg though. Both players were sitting on 2 bases the whole game, the Zerg was actually mining his second base first, yet the Protoss was apparently getting 2x the resources as the Zerg (?). This doesn't make any sense, especially since the Zerg expanded a second time. The only reason I can see is the Zerg guy couldn't produce enough drones while also producing combat units, which has always been a problem. If the Protoss can truly gain such a commanding economic advantage through conservative no-risk play it seems like a problem.
Also, the Protoss had no trouble building up swarms of units comparable to the Zerg. I don't have so much a problem with that except all of the Protoss units are clearly superior in a one-on-one matchup, so there is no upside for the Zerg there. Those Nullifiers are just disgusting with their apparently quite cheap force field ability they used over and over in the video -- Combine blocking off locations on the map with teleportation abilities of other Protoss and it is just sick.
