@ Protoss: i never actually thought of them as 'dumb' but i guess it kinda fits pretty well

, i guess though humans in the same timeframe would have likely had near xel-naga tech...
all the protoss really have going for them, is strong psyonic powers (which i asume takes MOST of their brains making them 'dumb' XD, i believe it is more likely religion thats keeping them behind than stupidity however.., which i asume that the zerg simply caught them by supprise (They have been top dogs for centuries, with no conflict), so i have a feeling that if they survive, much past their current point (sc3 territory?) they would evolve more desperate and successful means (although by that time, zerg will likely have taken enough protoss prisoners to construct psyonics of their own.
@Terran: well im sure when they made the SCV'less' extractors they more than likely just ran pipes... LOL, because im 99% sure they could have found a better use for teleportation than sending gas to the command center...
@buildings always flying&Battlecruisers should be round
well battlecruisers could be round, similar to the science vessle (which obviously didnt fly using boyancy)
I dont really think any of the buildings should fly though (esp using the propulsion systems they do.. and certainly not permanently, although its still something that plays to their strategy/lore (consume resources and move on), although i guess rocket ships can fly, so they could to technically... even if the fuel to take off, is likely greater than the raw material cost of construction of a new building (salvaging is a much more 'human' option)
@marines, the suits are the cheapest of the cheap, primarily to enable space combat, and enhance movement.. SCVS are probably way more expensive, so them being the 'same' price i asume is A) for balance, and B) because they factor in all the future ammo the marine couldever need, and combat training....
@Zerg: I believe they are atleast partially incontrol of the DNA, seeing as some animals/bodyparts have more IRON in their bodys, they could concentrate this into a 'shell'/weapons, although their ability to pierce battlecruisers with any such 'spine' is nothing short of retarded. concidering the velocity required just to reach the battlecruisers hight, not even pierce its 3-4 meter hull (unless maybe they were enhanced by powerful acids, which lore doesnt state, but would fit zerg lore well.. (it does say there slightly toxic)
My biggest Peeve is the ineffiency of some of the units...
SCV - no matter how cheap gas is, i doubt its cheaper than wheels so it wouldnt have to hover forever
Thor - there is no use for a giant siege walker like such that a tank type unit cant do for alot cheaper (wheels>robotic legs in price, durability, and speed, although slightly less maneuverable, rocket boosters would counteract that easily and still save a ton of cash
Colosus - I See absolutely no use for this whatsoever (even outside of wartime), however a dragoon with huge colosis legs (Granting supirior mobility) would be 'worth' its resourceconsumption (as you could get 20 for the same price)
Ultralisk - The amount of biomatter required to make/feed one of these must be enormous... and the only thing it theoretically looks good for would be taking out buildings (as a big battering ram), it wouldnt even help out taking choke point, as the corpse would make it even more dificult to get in...
My prediction is that zerg will continue to overrun the galaxies, with their rapid expansion, untill eventually the xel naga return, probably team up with the protoss (the ones who 'kept' closest to their word), and maybe even the humans for a time, to just about eradicate the zerg..
Now at this point, either the zerg win, or xel naga win, im leaning twards xel naga... but zerg will never be fully destroyed, because humans will likely keep some samples.. (plus the zerg that spread to far for the xel naga to find/destroy), and then the zerg will possibly absorb xel naga DNA, then were all fucked...
