so why does zerg get a broad multi-god catigory where the other two races only get 1 demigod.
Also protoss = beast? really? The beast is everything but protoss. He doesn't have shields, psycic powers, the ability to teleport (more than other demigods), arrogance, wisdom, sleek design, psychic crystals, love for gold, floating elements, etc. You know... the things that make the protoss. The protoss do not have 'heavy damage' anywhere in their high concept. They have 'strong' in that protoss have stronger units, but less of them... Protoss have no abilities that are similar to the beasts abilities. In that department Terran with Irradiate and Nuke. The beast LOOKs like a zerg and carries abilities in the same notion of SC1 queen infection abilites.
If anybody was protoss (which I do not believe there is currently a good fit) I would put it to be Oak. He fights along side warriors who previously fell in battle, similar to dragoons/stalkers/imortals. I feel like they say similar things at times. And his general appearance (clad in metal with very curved edges) is remotely similar in design.
Also, since you're saying "Starcraft 2" not "Starcraft in general", I would say zerg is inaccurate to 'micro intensive'. SC2 zerg is more commonly macro intensive, more than the other races. They do have large swarms, but there is very little 'micro' involved in managing them when compared to protoss and especially Terran. Terran is the most micro intensive, requiring some sort of micro control on almost every unit from stem-pack on the infantry, seige mode, thor's 'back-cannons', stealth, moving buildings, supply depots, fast 'micro heavy' reapers, move-fire-move units like maurader and helleon. Zerg only have curruptors and infestors, sometimes overseers if you're base harrassing. Mutalisks are heavy move-fire-move units, and hydrolisks are. Roaches are unburrow-fire-burrow units which are kinda awesome. But that's it. If you're playing zerg in SC2 (and winning) you are very likely more focused on managing your queens and hatcheries and just attack moving with your swarms of units expecting units and speed of unit production to overwealm the enemy rather than micro management. (the super pros are able to do both, which is why zerg is dominating in korea)
That being said, I do not feel like any of the generals really handle a lot of unit management and production. The many unit generals like the vampire and queen are the ones in particular that I think would qualify for zerg. The vampire does have the ability to use his minions to his benefit similar to the consume abilities that kerrigan wields. They certainly do not qualify as all generals, since generals like oak (just just throws down a marker and gets virtually uncontrollable air dudes flying around) and the healer cat chick (who only gets 2 yetis, hardly the 'smarm') do not share any qualities with the zerg.
I was running it off a 'high concept' state. like if you had to try to shorten down to what makes protoss 'protoss'. I don't really think "can demolish everything in its way if it does not get outflanked or surrounded" is something unique to protoss. I certainly would not place it as its high concept. I understand where somebody gets the idea of "few units, but expensive" because zealots and dragoons cost a lot more than early units avialable to the other races, but in SC2 that only applies to the zealot. The stalker is not like the dragoon at all as it is fairly flimsy and gets by on being extremely mobile and tricky with blink (not very beast like). Immortals are sorta similar to beast, in that their damage output is insanely high, but if you aren't bouncing off their hardened shields, they drop like flies. They also are not very vesitle in that they are slow and can only shoot ground. colossi have very long range and do very heavy damage, but they do not have a lot of HP. The only reason they seem to last long is because they tend to kill enemies before they get near. Its certainly not because they are tough. Void-rays do good damage and can move very quickly, but again they are very flimsy. Carriers, another staple protoss that was kept from SC1 because Blizzard felt that without "it just couldn't be the same 'protoss' " and it is NOTHING like the beast. Arbirters or Motherships, as well as shield drones and warp prisms, represent the high technology base of the protoss race with special force fields, clocking devices, and warping technology... again, nothing beast like here. I guess Dark Templar have that strike from the shadows thing, but they are very weak if they actually take any hits... I think the weakest of all protoss units in terms of durability.
Beast plagues people and does damage over time. I admit that 'tough and quick at the same time' kinda describes the zealot, its hardly a description for protoss as a whole. (and zealots are the foot soldiers of protoss... I have a tough time comparing beast to a "Teir 1 foot soldier") Protoss have high molibity because of their teleportation and chrono boost, but not in the same way the beast is. I understood you did not mean physical appearance, but I included it is a way of concluding they are similar, and they are not similar in that way either.
