I don't know. It seems Zerg got what they wanted, terran already had everything and protoss got some random gimmicky stuff.
Tempest - 300/300 AtA instead of carriers and mothership. Cool, if my silver opponent only makes mutas I can now counter them with Tempest!
Oracle - Probably the expected harass unit for protoss. Guess we'll have to wait for Reaver till LotV.
Replicant - may be ok.
Nexus recall - pretty cool.
Shredder - because ability of holding ground was something terran was missing...
Warhound - looks rubbish, but may be ok to compliment mech.
Transformer hellion - facepalm.
New Thor - because a single super-unit has proven to be what SC needs...
Viper - OP
New lurker - great.
Hydra buff - awesome.
Also opening DTs seems to be an auto-win against zerg now unless spire is not going to require lair any more which wouldn't make sense anyway.
Oracles seems okay, i'm not sure about replicant either. Them and mass recall will need some careful balancing.
Shredder will help a lot with ling harass, but so did PFs. I don't know if terrans needed any extra static defense. It's an okay addition overall.
Warhound's a goliath copy, and a replacement for Thors. It's a bit redundant, but not "rubbish" imo.
Transformer hellion, while a cheesy idea, can rly strength mech play and make those rine/helion attacks incredibly strong.
I do agree SuperThor is retarded
Viper seems awesome, but the "supposed" darkswarm sounds more like disruption web than ds. The new "lurker" is noting like lurker at all. More suited for breaking siege lines than killing marines imo.
Hydra and Ultra buff was needed from the beginning of WoL, so good buff. Baneling burrow move seems rly strange, considering u can use banedrops.
