Well, I disagree. Not that I even want this change to happen, but for argument's sake:
Yakk wrote:It would require more money up front
When I build corruptors, I gauge my gas income so that all of them can morph as soon as they finish. No one can perfectly gauge it 100% of the time, so brood lord production can be staggered, which is suboptimal. Coming directly from larva removes that problem entirely. I don't care if I have to pay more up front when I bank the resources to morph them anyway.

You wouldn't be in a position where you'd want to. Corruptors aren't too good against anything. Maybe you could get lucky and a protoss does a stargate heavy attack on you just as you switch into brood lords, or something?.. Meh, you should have seen it coming from a mile away and have not gone towards brood lords at all, but even if you didn't, a handful of corruptors aren't going to do a whole lot to save you.
Yakk wrote:you couldn't move them around as fast-moving corruptors to a staging area then upgrade them to broodlords.
That's valid, but I don't see it as a big of a deal as the production problem I mentioned above. One could have a hatchery at the staging area purely for brood lord production so that they're always safe at a negligible cost. On some maps you wouldn't even need it though.
Yakk wrote:Nor could you build corruptors, take out the opponents air force, then morph most of your (now useless) corruptors into broodlords.
When does that actually happen? I think the last time I've seen that happen was when corruptors had contamination back in the beta.

Well, I'd say that that's the problem. Those corruptors are taking up gas and supply and not making themselves very useful until they're morphed. Thus, skipping corruptors in the production of brood lords would be a small buff.

This doesn't directly affect the weakness of brood lords to air-to-air forces, but in my mind it's another point in favor of having the particular setup that zerg have with their late-game air units, regardless of the weaknesses of the individual units.
Eh? By micro options, do you mean micro requirements for equal efficiency? I mean, if the marine was split into two units, one that fired only at air and one that fired only at ground... You'd have to micro them to better fulfill their roles but I'd never consider that an inherent strength.
Though you reminded me to mention that I don't find brood lords to be on the same level as as battlecruisers and carriers. 10 brood lords and 10 corruptors is a tough army, but 20 carriers/battlecruisers are unkillable without a very deliberate counter.
