I have such generals: Badoglio, Fletcher, Guderian, Konev. And it's obviously, to hard to fight by Guderian only. And I need help in choosing tank general.
I dont want to buy Rommel, due to almost useless skills Desert fighting and Ace forces(currently, my panzers are 3 lvl and they will be ez uprd more w/o consumption of industry, so this skill definitely not so useful). Thereby, only his strengths is Tide of iron 4!
As for Patton, he is much more closer to second tank general spot. His strengths are Blitzkrieg 3, Explosives 3. But I will say 2 reasons, why he is still not good for conquest. He hasn't Tide of Iron and Supply! After losing 50% of health, he can not adequately fight! Street fighting is great only for Hold the ground challenges, not for active steps. And he has almost useless Ace forces with upd troops!
So, ignoring Patton, we have Rokossovsky, Montgomery and Vatutin.
Vatutin has only 120 hp and only 1 mp. His strengths Tide of iron 4 and Plain fighting 2, and Supply 1. So he is not for conquest.
Weaknesses of Montgomery are lack of fifth panzer ability star, Tide of iron 1, almost useless Desert fighting. But he has awesome HP:280, Supply 4, and four Air stars, what pretty nice for tank general.
Weaknesses of Rokossovsky are lack of fifth panzer ability star, and lack of fourth lvl of Tide of iron. Also, he has 4 star infantry ability, which is much more worse than the same Montgomery's 4 star, but in air abylity! He can be a very bad infantry general for price 3480 medals with only 2 dmg from Guerrilla! But He has a pretty good survival rate: 280 HP, Supply 2, Shelter Expert 2 and decent speed(4 squares per turn on super tank)
I'm glad to see your opinions about second and third tank generals spots!
