StarCraft, to be a true sequel, had to remove units to make place for new ones. Do you agree with who was cut? Why?
In my opinion, the right choices were made when choosing which units will return and which should not come back in StarCraft II.
Firebat: He was decent back in the days but seriously who really used him a lot. Most player simply used him as a "support" unit while doing MnM against Zerg. In any case, I always thought that using a flamethrower was pretty uninteresting as a unit's weapon.
Medic and dropship: Well since they got mixed together it's ok with me.
Vulture: Here is a unit that never should have become so used on the battlefield. The vulture was supposed to be a scouting unit, not a unit that you mass to counter zealots in a TvP match. Furthermore, spamming the whole map with mines is something terribly annoying.
Wraiths: They sucked at atg and their ata was decent but then again why use a wraith to counter air while you can make a Valkyrie or a goliath?
Goliath: The goliath was ok but really needed something to make him more interesting, that something was everything the viking can do. The viking is a pretty interesting successor.
Valkyrie: Only used in rare occasion against mass air. It's kinda getting more popular with the fantasy build but the design was just meh imo.
Science Vessel: Useful unit but god was it everything but cool. It's a flying building... Really not interesting.
Guardian: Replaced with a better guardian? Sounds ok to me.
Queen: Not really a popular unit, not really good looking either. It had some interesting abilities, but her coolest ability was barely ever used (infest cc).
Scourge: Really didn't help at making air units more useful. Enough said.
Defiler: Dark Swarm was an annoying crap. It make useless almost every unit in the game.
Devourer: That's supposed to be the response to carrier and bc? lol. You're better with dark swarm + hydra. Furthermore the devourer is so not cool.
Dragoons: Honestly, they were ugly. Useful yes, but not bad ass enough for me. I'm glad we now have stalkers and immortal. They are way cooler.
Scout: Most likely the most useless unit of this entire game.
Corsair: Good unit but wasn't really symbolic enough to be kept.
Reaver: Way too hard to micro for newcomer because wow you need to build scarabs, use a shuttle to move around and since the scarabs are retarded, place your shot well. Every units should be easy to be used but hard to master. This unit is hard to be used in the first place.
Shuttle: Wasn't original enough. Warp prism is a worthy successor.
