I was impressed by your play early on and by your teching choices. As I was thinking what tech path you should go, you went it. However, you made a CRITICAL error in choosing infantry doc too early. You should be certain on the Wehr player's tech path before choosing so you can counter it best. Airborne would've been perfect.
When the Panthers started rolling out and the MGs were still camping in the buildings, you should've spammed a few AT guns and gone for snipers. Shermans can't compete with Panthers at all. AT guns + RR airborne should've been your counter, while snipers picked off the MGs. The Shermans should've just been your counterattack after disabling/destroying the Panthers so you could chase down the Ostwinds. I have to say that you deserved to win anyway. His Ostwinds were unusually effective, although you did tend to blob a bit, especially when going for a sticky plant. Such mass charges won't ever work against a higher up player.
You floated a LOT of manpower midgame, which I guess you decided to spend on Rangers which was a bad choice. This should've gone toward Snipers and AT guns, and a 2nd M8 would've been nice too. A word of advice on the M8 - never send it in without getting skirts first. Skirts should always be researched before MG. You repaired all your vehicles well though.
Early on, you had good avoidance play and capping but didn't handle the MGs in middle particularly well. You should practice a few flanks using flamers. Going M8 was a wise choice though.
Overall, you generally played better than him but made 3 critical errors as I saw it:
1. Chose doc too early, and infantry was wrong choice.
2. Lost 2 Ranger squads in 1 battle at an important stage, left side of map.
3. Failed to counter MG setup and Panthers after they arrived. You needed to make use of Snipers and AT guns as I said, or airborne could've supplemented your Shermans nicely.
Things you did well:
Tech path - up until the Panthers arrived you teched correctly.
General micro generally, and good avoidance gameplay against MG spam.
Good repair micro. Reasonably good timing on vehicle retreats and vehicle micro.
Minor things to improve:
Exiting buildings - lost a rifle squad at start when exiting from wrong side. I always try and specify which door/side to leave from.
Micro in big battles - lost those Rangers. Also, neglected Shermans a little when microing riflemen to throw stickies.
Flanking MGs with flamers - essential early game skill.
If you get into an argument with me, you're wrong.
