I’ve attempted the G1 DOW, but with less force. I knew I would get counter-attacked and lose BS/EP back, but then I’d be able counter-attack again and retake them for (hopefully) good. My thought was it would be more beneficial to kill the Russians sooner than let them retreat and gain strength in numbers. However, with a Sea Lion purchase I ended up short on ground troops early and had to lose some tanks to take Leningrad - didn’t like that.
I like seeing these ultra aggressive strategies - but from my experience I would definitely have preferred the extra ground troops on the Eastern front early on. As others have mentioned, the NO money trade-off sucks as well. Giving the USSR a free 5 IPCs every turn until I was able to get Archangel (no subs left after G1 attacks) while losing yours by waiting til G2/3 on normal Sea Lion feint.
