[quote name='Clak']On the MULEs issue, that faster collection rate also makes it a lot easier to expand, since the cost of a new base doesn't sting as much with all that extra mineral. If it gets destroyed it isn't as big a deal. Hell, some people build a base to wall in their main if they have a lot of extra mineral.[/QUOTE]
But holding the expansion is very difficult. It is a pretty big deal if you transfer SCVs because those take a while to build up, and depending on your macro it could really slow your production down, 2 gas makes a big difference for Terran.
PF requires 150 gas, and the armor upgrade is another 100 gas, and the build time takes a while. And if you have PF, you can't mule.
Bunkers and turrets are expensive, and you need to walk your troops over to the bunkers which is why you never see them used for expo defense.
Protoss can warp units in, photons hit air and ground and act as detectors, you can chrono probes fast if you lose them, and it doesn't cost any gas for them to set up. It's easier for Toss to hold their expos.
The advantage of faster minerals (which really kicks in mid-game) usually only means more marines and harder to hold expos. It's not advantageous in any way.

destroyed by concussive shells if there's room to kite (unlike zerglings, where only a few of the roiling mass will be affected,).
2: Being melee units, their attacks don't scale up in the same way that marines', hydras', etc. do. Hell, even once we've closed the gap and half our boys have been shredded, that just means the marines stuck in the back row can get their shots in, too.
3: As noted above, they are only useful when they receive heavy support from other units (which is a pretty common theme as far as the protoss army goes), and upon entering the "I have a jillion colossii and he has, like, ten tanks and so many

ing MMM my computer slows down when they all stim" phase of the game, they get to be full-on

Equal chargelots should kill equal maruaders, I think (and Marauders cost more). Kiting is a huge APM sink, a Toss just needs to A-Move and then he can do other things like base management, micro other units, etc.
And even though they act as bullet sponges, they are very good bullet sponges. Unchecked, they will tear through the army if the Terran does not focus fire them down since they have more DPS than Stalkers.
The guy who made siege tanks?
At least with a tank, the gigantic turret's rotational force might affect the aim and movement.
A hellion has a tiny ass flame cannon on it! Can you imagine in WW2, a Sherman stopping so that the gunner can squeeze off a few bullets?
I think they only reason they make it stop is so it doesn't look as stupid as Phoenixes.
