its not that terran is overpowered..
its becoz not many ppl is using zerg, hence the exploration on the units is low..
and great units such as infestor is under used..

tht biomech ball is uber freakin hard to counter if you're a zerg player. sigh. thors are so hard to kill.

plus the wall-in. with siege tanks and then use banshees to harass.

Rofl! Never thought of this before!
Nobody will compare it like that. The game is not only consists of first tier unit. They are not the only unit you can build.

People keep complaining about Stalkers being more expensive than Marauders but couldn't beat Marauders 1v1. But there's no rule saying that you must use Stalker to fight Marauder. Besides, Stalkers can attack both air and ground, yet when people keep losing them to Marauders on ground, they complain.

When a Terran player mass Marauders and then lost to a Void Ray rush, they should complain too: "Why Marauders can't attack air? Wtf? Why Stalkers can attack air?".

Melting a Terran bioball always has been a thrill for me.

yes it is!!! omg.. 

but if it fails. GG.

Overlord = cost only 100, needs no supply space, can be used as a transporter and a scout..

In BW, for me Overlord is the most value for money unit as it can also detect cloak units.

Overseer = u can use to spy with channeling and u can use it to halt productions

Infestor = mass infested terrans

nydus worm = u can place it anywhere as long ur unit can see the location
early rush = 6 pool rush, 10 pool rush
pre-midgame rush = baneling bust

Zerg has many harrassment tactics too..

3. u die before getting HT as agreed by the pros (and mid-high diamond)...
u take a early robo no matter wut due to the banshee styled builds (polt timing attack even need u to go 3-1-1) as well as to scout early on...
and even when ur colossus get EMP, u sitll have dps unlike templar...
archon getting emp-ed = 10hp crap...

id assume ur not a TL forum visitor wwww

dont have to be. but they do have pretty much everything you'll want to know for SC/SC2 (remember wiki.teamliquid.net? lol)

Quote Blizzard:

Here are a few of the changes we currently have planned:

· We're increasing roach range. This will allow roaches to be more effective in large groups, giving the zerg more options in the mid to end game.

· Fungal Growth will now prevent Blink, which will give zerg a way to stop endlessly Blinking stalkers which can be very challenging to deal with in large numbers.

· The Barracks are going to require a Supply Depot, which will impact a lot of early terran reaper pushes.

· The reaper speed upgrade will require the Factory, which is meant to weaken a lot of the early terran reaper attacks that dominate so many matches, especially in team games.

· We're making a number of increases to the health of zerg buildings, which will make the very vulnerable zerg technology structures more resistant to raids. We don’t expect these hit point changes to have a super significant impact on the game, but the current numbers felt way too low.

there are reasons why those 2 units should be compared
ultras are supposed to be hard counter counter for armored units ... thors are more of a utility kind of unit ...
food count is the same, resource to build is the same ...
logically, ultras should own thors ...

come to think of it, maybe thors are OP ... they'd even gun down BCs in a straight fight ... i guess they need a big nerf
