If you think this is useless you're batshit insane.
Starts i've done that work epicly well:
-2x IST, 1x 50mm, 1x FSJ Tank Buster, 1x Ketten (No longer works because ketten is 2 pop, but I guess you can just wait for the extra 1) Is extremely offensive.
-2x Hotchkiss Stuka, 1x 50mm, 2x FSJ with FG42 + Faust (Entire company is based around hotch stukas, would end up with 50-60 kills between them each and every game. Works well if you like playing as a support player, both defensively OR offensively.
As a rule now I generally always start with a Vamp HT and Muni HT. The beauty of this start is that it is completely self sufficient. The ability for +6 pop on Luft is infinitely better than +6 pop on Airborne. The only fun thing about Raid was running 2x Shermans, 1 atg and engies with mines when I got to 32
.
Not to mention, end game you will be at 44-46 (For some reasons some games popcap would be locked at 44?) pop. Not bad eh? The downside of this t4 is obviously if you don't plan for attrition, you will run out of units somewhere between the 20-25 minute mark, about 5 minutes faster than you normally would (at least for me, this has been the case).
Oh btw Wirbels with this top are incredible. I look at the tree like this: The t3 contains all the heavy buffs that you will find useful, and the t4 is basically just +6 pop. Grenade/faust recharge is nice, the LATHT cloak is nice, but they don't really do anything that you'll need.
