After the match, I was thinking I should have gone Guard Motor for 85's, 120mm Mortars, and maybe tech T4 and get a Katyusha to counter those pesky double ISG's that were destroying me over time. Mechanized Support was the worst commander decision I could have chose. Due to the fact I veto Langreskaya, Minsk, Crossing, and Road to Kharkov, I really shouldn't be using that commander. I struggle against defensive playstyles and tend to lose Wars of Attrition. I also forget about how powerful demos are against OKW. My problem is not adapting when stalling for Call-ins isn't going to work. I need to know when to go T4 to apply pressure or when to wait for Call-ins. I tend to be too hard on myself for mistakes and it often sinks my play.
Thanks for the tips though!
