Why go pure mech?

General Discussion
I have never seen it work. Why do people even try? A mix of both bio and mech is always better.
Pure mech is good if you can hold off any pushes or major harass while using your hellions for map control and harassing the enemy. Every time you make a batch of hellions and suicide them, you're making room for your siege tanks and thors. Pure siege tank thor is the ultimate mech composition, but it's not possible to get there if your opponent is constantly harassing you. Pure mech is insanely powerful, you'll see it at higher levels.
Im not good enough to pull it off but I have seen pro's do it before.
Terran Player go pure mech because:
1) Pure mech worked very well in Brood War. The composition should still work in Starcraft II if Factory units are actually balanced.

2) Mech units are not "support" units like Colossus or High Templar that make up for any deficiencies in the army (e.g. Protoss Gateway armies use Colossus and High Templar to make up for their dps deficit). Siege Tanks, Hellions, and thors are sufficient to build the core of an army, similarly to Bio units and most Zerg units. The real Terran "support" units are Ghosts (anti-Ht/Protoss), Vikings (Colossus and air defense deficiencies), Medivacs (transport/bio), and Ravens (detection, seeker missiles, point-defense).

3) Terran upgrades and production facilities are heavily split, so once a Terran player starts investing in production he/she cannot make fast transitions to other production. Every production path has to be self-sufficient or it is not viable.

There are two problems with mech:
1) Current Terran mech units are too weak to actually fill their roles. This includes Siege Tanks, which are not strong enough for their ground control role. Just a note about those who say Siege Tanks are not weak: Many of them would still consider the Siege Tank "strong" even if it did only 30 flat damage just because of its design.

2) Mech has always been difficult to build up safely because it requires a large initial investment that it is currently too weak to hold.
Savings on engi bay upgrades. Also, faster neosteel frame.
largely because of the gameplay difference. same reason why protoss really want viable stargate tech: to be different.

the problem with mech in SC2 compared to BW is that the things you need to have mech work (good area control namely) are absent or much harder to get with pure mech.
Pure mech is actually insanely strong. If you go mass tanks, thors and hellions with maybe some viking support, it's one of the strongest compositions in the game, especially against zerg and often against terran too. So strong that it's often impossible to engage the army head on.

The problem is building the army up. You generally need to buy yourself time with hellions, banshees, etc because you are vulnerable early. It's also an immobile army so you need to make sure you are defended from drops and counter attacks back at home. Once you are set though it's very very powerful.

There's a lot of pro players that use mech quite often vs zerg and terran, and it works a good percentage of the time too. Hell Sea beat Naniwa in IPL in a TvP using mech O_O
Then you can put more resources into the mech instead of bio upgrades. Bio needs their separate attack and armor plus medivacs, stim, conc and combat shields. That is actually a large amount of gas you are taking out of making your mech army.
why upgrade bio armour? it doesn't help at all against banelings or fungal or storm or archons or colossus (ie anything that beats bio)

have you considered bio/mech with double attack upgrades? (maybe get +1 armor at e-bay because it is cheap and helps out before critical mass.

kinda like the funky mixed build that marineking used to do occasionally.

Mech armor is actually better than +2 attack until you start using thors vs corruptors and Broodlords. Hellions and tanks benefit great from +1 attack, but except against ultralisks, +2 is not as huge.

Bio armor help agains't the core of the oponent army, namely: zergling, stalkers, zealot, marine, infested terran, etc

Units with low base attack are especially effected by armor (marines and zergling lose a lot of dps when they face oponent with higher armor)
Reasons to go pure mech:

1: When your banshee hellion opening somehow does a lot of damage and you want to shame the Zerg for being bad.

2: You are playing TvT.

That's all I've got.
Roaches and Immortals
It's viable in TvT because BF Hellions roast Marines, and end the game if you can get them into the enemy supply line.

It's viable in TvZ because Hellion Thor Banshee Viking counters every single Zerg composition. It takes a lot of time to build up, but once you get a 200/200 deathball with SCVs for repair and hit 2/2 upgrades, it's gg.

It isn't viable in TvP if Protoss scouts what you're doing and reacts. But if toss goes for a standard anti-bio unit comp, here's a nice guide to mech: http://www.teamliquid.net/forum/viewmessage.php?topic_id=378181
The way I've see it in pro matches, bio is a more typical build. It can be split up into smaller groups, drop harass, prong, and do single large scale engagements. But it's strength is divide and conquer, generally (including flanks).

Mech is the spear of doom. If you can hold off aggression until you have a sufficiently meaty mech force, your opponent HAS to deal with it. You park that mech army just outside his base, he is forced to either defend, sit in defense, engage and try to push you back, or do a base race. It can't harass or prong as well, but you setup right, and it's a suicide engagement for the enemy, especially if you contain.

Though you are right to an extent. A mix of bio and mech has better versatility. It's all a matter of playstyle.

sky terran is an example of this. and it was quite viable. probably still is in certain leagues
It works vs Terran and Zerg.
Bio backed up by tanks seems more deadly than pure mech in tvt. Marauders are good against both tanks and thors, and are strong enough to out damage hellions.
