SO essentially, guess their strategy and overwhelm them early. I agree about the tanks, it just seems like a too late too little battle. Do pak43 commanders tip the tide vs the tanks or would that just be suicide with all the arty and planes?
Depends on the skill level, usually the pak43 gets instantly destroyed by offmaps. Also the doctrine kinda invites you to turtle in - you want to omit that, you want an aggressive map presence, not just focus on one spot.
In 2vs2 I usually veto any map that has bottlenecks or is too packed(tros ponts, düsseldorf, semoski winter, ettelbrück, lierneux), because you can't flank and spread your units on such maps and most importantly you can't dodge arty on such maps.
