Here are a few that I can think of:

1) Why SCV can be a mechanical and biological unit at the same time (which explains why scv can heal scv)? While Thor / siege tank is pure mechanical even though inside them there's a biological creature (human).

2) Banelings don't do splash damage to friendly units but Siege tank does.

3) The patch of supply depot requirements to do barracks shows how they desperately wanna make the race balance and doesn't follow terran's fundamental laws.

another one:

drones can pass underneath queen when they are sucking minerals, but can't pass underneath queen when they are far from mineral lines..

what i meant on the 1st one is that why scv is both mechanical and biological (can be healed by scv and medics too) whereas units such as thors or siege tanks which has humans on it just like an scv is not considered both mechanical and biological..

i mean it doesn't have to be scientifically proven, but the laws they made is not consistent..

For example in Windows OS, just like in a window, u can see the standard close button at the upper right, but suddenly when u open another random window the close button is located at the middle of the window. Not consistent and rhythmatic.

+1

if they do that, definitely they have to buff all the small units

haha, some sort of flying banelings..
