I'm a Protoss guy, so I love the Tempest. Skytoss is now a very fun and viable strategy and I'm very glad they decided to keep the Carrier in the game. What I don't like is that in team games with a Protoss on each team, more Tempests = win. In smaller engagements, you can micro your Void Rays to take out the other Tempests out or your Carriers can survive enough to do some damage, but in a 200/200 supply slugfest, whoever has the most Tempests simply cannot be touched. They massacre carriers and a split void ray/tempest composition will get splattered by all tempests. Oracles are great, but you have to sacrifice a lot to get them; IME, if you don't win outright/seriously damage their economy with Oracles, you lose. A lot of times I've lost when I went fast Stargate and had two Oracles and simply got rolled by 4gate/3 rax/roach timing/whatever. Core is nice but its defensive abilities can be evaded easily enough and I'm not aggressive enough to really use them well.
I remember Swarm Hosts being pretty viable in the beta with players spawning creep with an overlord in a forward position and then throwing down a few spore/spine crawlers with ~5 swarm hosts. Combined with speedlings it made for great map control, and given how long it takes for Zerg to get siege units otherwise (Brood Lords) it still could be viable. The Viper sucks really badly, but Hydras got an awesome buff. Some of the Terran buffs are really nice, like what the Medivac got. Hellbats are great with the medivac heal, but there are a lot of Terran units that still have no purpose (battlecruiser). The Widow Mine is friggin' awesome and borderline overpowered; considering the damage it provides for 75/25, while burrowed, hitting air and ground, from a Factory without a techlab... excellent. Plant a few in your mineral line and watch your mutalisk problems explode - nevermind how devastating they can be if you can sneak a few into the enemy base...
I like HotS overall, but I feel like it could've been much more. The new Bnet revamp is nice, but the game still plays exactly the same - Protoss is still a-moving giant deathballs, Zerg still needs to stay up 1 base and creep-spread like hell, and Terrans are still doing bio + drops. Its fun, but kind of "meh," and to be honest I expected more after nearly three years.
