I have a question: What is the going bid for BM? I’m getting back into it and I’m curious as originally the goal was to eliminate bids but I think they’re still around?
As for the increased costs to bombers, for what it’s worth, I think an increase to 14 makes sense. Every single unit in A&A has had some cost or attribute change since the original game (if you count inf getting the art bonus hehe), so it makes sense to reconsider value from time to time as the game evolves and strategies develop.
Personally I like the sbr bonus at 2 or 3. What really makes them overpowered, in my opinion, is their airbase range. Not saying that should be changed though as that would have a huge impact. I still remember the long ago forum discussions around weakening the defence of ACs from 3 to 2, and making subs weaker on defense, and 2-hit battleships. Great discussions to have and good ideas often flow from them!
