In SC1 Protoss had the greatest space fleet in the game (lore-wise). I didn't get that feeling in the actual game so much, but, hey, scouts had the best air-to-air and mass carriers = instant win (that's how it works, right?). In the original Starcraft and in Brood War, I always loved going air as 'toss, more because of aesthetics than anything else.
All that changed in SC2. Protoss seems to have the worst air units as well as the most to fear from the air (although I hesitate to use words like "worst"). I'l break it down:
Phoenix: unit for unit, they will lose to corrupters and vikings, and can only harass with constant micro (not a real problem) and energy (which runs out fast). They are also the only "raider" aircraft (like the banshee and mutalisk) that cannot attack buildings (unlike, say, mutalisks which can just overpower turrets in numbers). Blizzard has tried to make them more viable by making them build faster, but do we really want protoss's main air unit to rely on quantity over quality?
Viod Rays: these used to be almost exclusively "cheese units", until a couple nerfs severely reduced void ray rushes. Unfortunately, That also reduced their capacity as AtG attacker that the phoenix did not have (despite being the AtA and raider for 'toss combined). I've seen VRs used in legit play a few times, and it makes e hapy to see them, but they still are pretty awkward and their role is nebulous and ill-defined.
Carriers: I love carriers. Unfortunately, they're just not seen hardly ever. I see plenty of Brood Lords, but no BCs or Carriers. They seem to only be effective in large numbers, and with vikings able to be reactor-pumped and late-game zerg almost always going b
Mothership: the Mothership is a great idea for protoss. It looks like it's finally found it's use too. Unfortunately, that use seems to be expansion defense/recall help for a trapped army. Doesn't seem like an awe-inspiring ship to me.
Sorry, that got a tad long-winded, but I tried to keep QQ to a minimum. Anyway, my point is that Protoss seems to excel in ground units and hardly ever takes flight, whereas almost every zerg gets a spire (even if jsut for mutas) and most terrans I see incorporate vikings, medivacs, and banshees. I don't mind 'toss being a more ground-centered race, but it seems contrary to their theme from SC1.
Please, tell me if I am missing something, or what?
