Now the thing about force fields is that it's usually used to block out ramps or dis organize formations from the opposing team, now what if we can used it to protect our team mates siege tank or vice versa?
I couldn't check if i was able to attack that particular siege tank while it was still inside the force field. but if someone can try this on 2v2 while Protoss and Terrans are allies that will be awesome and very kind of you.
Sorry if it's not really super detailed, but I think I've already provided my point.
Btw, I think the benefits are:
melee units can't attack you since you're inside the force field
or zergling/zealots/ can't surround you that easily.
