There is also a custom map floating around that replicates the new units of HOTS so you can try them out I am very much liking the new Protoss units, especially the tempest when it comes to going against mass Zerg Air

Yeah I saw that. It's a bit different I'm sure, though, since it was most likely made by a third-party. I like burrowed banelings moving.

I started hating carriers in SC2 personally though, even if I'll still miss them in some ways, because when people went mass carrier it caused some ppl with older computers to lag the game like crazy.
