Certain tactics are all but unassailable in LL. Almost every crack pot, insane idea I’ve had for a strategy in AAR has worked flawlessly in LL but been crippled in a myriad of different ways in ADS.
That’s probably do to the spiraling effect that the luck of the dice bring.
Losing the battle for Stalingrad does not only effect the battle for Stalingrad. It effects what your allies have to do to help you recover, it effects your builds, your position, what you have available, what your enemy can do, etc.
In LL, if you lose a battle you initiated, it’s never going to be a devastating loss (unless you failed 3rd grade mathematics.)
