Strat bombing seems to me to be the biggest game breaker to fix in this patch. If you get a deadlock by 1916 or so, it's the only thing that ends up counting - a crazy back and forth of fleets of bombers until one side or the other withers away first. The land war ceases to have a meaning. I love the 1914-15 game, but after that, it's broken - and I really want it fixed, because I do love the game. I've just had another game end on an agreed stalemate because of this.
Two possible fixes are to 1) dramatically decrease effectiveness (e.g. only 1 in 5 strikes of a Zepp does -1, and maybe 1 in 3 for a bomber), or 2) impacts NM only, with no effect on PP (and NM impact would have to be low and probably on a diminishing curve).
...or better still just remove strategic bombing completely. It wasn't a factor in WWI, its a boring element of the game anyway - as you say its just each side sending waves of planes over - OR if you are to keep it in, make it affect morale NOT production.
Here is a few suggestions to help reduce effectiveness of massive strategic bombing campaigns.
1) After each strategic bombing mission the bombing units gets a loss in efficiency.
2) After each strategic bombing mission during winter there is a risk of loss of strength points in addition to the efficiency loss.
3) Fighters interception range increased.
It is my understanding that the weather was a major threat to zeppelins on bombing missions. I suspect that bombers were affected during bad weather as well.
