In relics explanation of the ability the plane is extremely weak to AA. It flys over the enemy base every time!
If all the soviet is doing is spamming shermans, they should not come out any sooner as they still need 9CP which is much later than having enough fuel. It would however mean they probably have enough for 3 straight away.
True, but Shermans are almost useless against proper Tiger/panther play anyways, and 9 CP gives plenty time for T4 and Panther to be built, and a huge opening for scout car abuse since LL doesn't have guards.
I think the Biggest obsticle to defeating LL is similar to Soviet Industry. Finding out what doc the Sov chose and making counter preparations before the swarm of tanks come.
