Some quick thoughts (first feelings - best feelings):
Terran
- Didn't understood the Cyclone. Kinda strange gameplay.
- Liberator is too strong AG while is too weak AA, very likely to be nerfed/buffed
- So many upgrades! They added about 3 new upgrades and splitted armory upgrades. And it's all after the reduce of resources on the map...
Zerg
- Ravagers are so weak. And their ability is too hard to hit a target, so it's like only effective vs static defences.
- Lurkers are good!
Protoss
- Don't understand Adept at all. It's like a new Reaper.
- Disruptor is good!
Overall
- Don't like the reduce of resources at all! We need more resources, not less!
- Like the 12 starting workers and increased limit given by Nexus/CC/Hatcheries, just feels better
