No one in my group likes the new “roll for convoy damage” system so we went back to set amounts: 3 IPCs for each German sub, 2 IPCs for all other nation’s subs, 2 IPCs for each carrier borne aircraft (meaning you would have to leave a carrier just for convoy raiding) and 1 IPC for any other warship.
I have to agree with Young Grasshopper on this one. With the latest setup, it’s next to impossible to wipe out the British fleet unless you get outstanding dice rolls for Germany and really crappy rolls for UK. Even if you leave the DD/Trn in SZ 106 and the CA in SZ 91 alone, you still have 5 subs, 1 BB, 4 fighters, 4 tacs and 2 strats to hit 2 BB, 3 CA, 2 DD and 4 fighters, depending on where UK scrambles them. Some of your units are limited in which SZs they can hit and since UK doesn’t have to scramble until you finish your combat move, you could end up with a nasty surprise in either SZ 109 or 110, depending on how much you committed to either zone. You may be successful in sinking all the ships and even killing the fighters, but you will end up losing A LOT of planes and subs in the process, perhaps even your battleship.
