Very good, thank you man! How about teching for a 4 player axis team? Is it wise for a couple to stay invested in tier 2, while others quickly tech to t3 and t4?
Also, commander recommendations for the wher?
Its been a while since ive played so my commanders might be off but I'd recommend something like Lighting war/Elite Troops, Mobile Defense, Jager Infantry.
For OST id say a fast t2 is always good. Depending on how the match is going you can skip t2 for a fast p4. But if you fall behind in fuel just know that their will get LVs and tanks out fast so a t2 into paks is a good idea. OST t4 is a good pick up in 4v4 because the pwefer is great in 4v4. Similarly your teammates can pickup the slack if you rush it with their own vehicles. t2 into t4 is good so you still have anti vehicle similarly a fast t4 is good when using Ostruppen doctrine. Panthers get countered against TDs though.
OKW t1 or t2 is solely based on play style. Luchs comes out fast but has a smaller window in 4v4 but can be very effective. Similarly the flak ht if micro'ed well will scale great since its a counter to allied air superiority. Also Liegs are good for breaking up defenses.
