Tbh stops the attack, that’s okay, but when you lose the whole group of units or its 90%, it becomes sad, you realize that just all of your economic advantage was buried

I understand that it is necessary to build up anti-air, it costs as much as 1350 metal for the group, so that on average it can protect the group. In general, on closed corner maps it’s not difficult to build up an extra advantage of 1350 metal, sooner or later I will be able to get an anti-air group, but on spacious maps, with easy hillyness, it’s much harder to defend against tbh. The first received tbh is capable of destroying spots that are closed by a stinger + 3 llt or destroying groups of units that have not yet increased their mass

I don't understand how izirayd can complain about balance if he plays the exact same units, first and second factory every game.

Some units, including Thunderbird, are designed to beat shield balls. So it is supposed to force the shield player to split up their units.
