It is because arc is shown from center of building while mg range is from window.
it pretty annoying for other player because he see arc know where he should not go while flanking but...
Well, somehow I did not notice this during XXXX hours of playing, so I think it has to do something with last patch, becasue in this case, I noticed it right away.
No, Its called brutal misuse of your units. if you believe the puma is capable of taking out tanks from the front then show. but i know you will not. your strategy requires you opponent to be complete idiot or is in a coma.
Make first building buildable by Engis, but while the first building is complete, there will be free "engis" from it (like medics or engis from MedHQ/MechHQ) which can only build builinds in base.
When I'm back from work, I like to relax and play non-intensive 4v4 game.
But currently it's just pudding. Every single 4v4 as OKW I won so far without any effort (1 defeat at the begging, you know, stun at 0:00 and then suddenly drop).
On the other hand playing as allies in current state...
