Just limiting you ennemies moves doesn't mean you have won...
Doing that with only taking cover right now and clever player placement/variety, pretty much does.
Oh, other than having a gang of supermuties.
Then we will have some years to wait before new features.
It's a beta. Ofc new features will be abused. We have to implement it to be able to fix it.
Not really...but is there a point in implementing a feature that needs to be dumbed down to oblivion so that it is of use without being an abuse fest ?
There is no need to break TC more than it is right now.
I'm not saying that there isn't a need for more variety right now, but giving players an absolute choice as to what to block isn't a great idea.
Besides, I don't see the point. There is usually enough cover to restrict enemy movement if you are smart about it.
Giving even more power will just make fights more unbalanced.
Only 3 sandbags are needed to camp Gecko's scrap yard for instance

Im sure the same can be said for other towns.
Even if the sandbags can be destroyed, they would still give an epicly unfair advantage in this and other cases.
Of course, this is all in my humble opinion.
