The inability of you being able to read the charts properly reflect poorly on your countries education system.
The the OP of this thread. The poster of the stats made a mistake and has corrected it in his OP.
I read the chart and it is stupid to say "This data ergo Axis OP". Its just as stupid as "the OKCupid stats, showing men of all ages showing preference in young 20 year old women, ergo all men love young girls" Your inability to understand the data reflects only on your poor comprehension.
As someone who has been in the competitive gaming scene for almost a decade, with over 1k hours of CoH2 played, I can tell you the data doesn't reflect reality. Allies out class Axis in every way. Allies early-mid game allows them to beat Axis to late game armor, which is the only area where axis is "better". USSR's T1 + T2 into ISU dominates. Only JT and Elefant can effectively counter it.
USF has some of the strongest infantry in the game. While lacking a heavy tank, their Shermans make up for it. Their Shermans are cheap while remaining strong. Their radio net passive helps increase their power as you get 2-3 of them. By having multiple Shermans, you can exploit the weakness in German armor, their slow movement and turret rotation speed. The bigger the tank, the easier it is for Shermans to swarm it. This synergies with ISUs as the Shermans can effectively take out ele/JTs.
The only reason Axis "seems" OP is because it is easier to play, especially their tanks. Noobs like to go head to head with tanks. While you can do this with German tanks, you need to play smarter with Allies tanks.
