The only reason I really liked Trinity was due to the fact that it wasn't easy for the factories to be pushed back, meaning I could up to hit them without having to deal with 163's so quickly. There are some other maps that do somewhat offer that, but the factories were easy to push back. On Trinity, there was a little effort required to do so. I'd like to see Trinity brought back, but maybe lowering those mountains would work? The only mountains that should stay 30+k are the ones surrounding the TT there. I would have to agree that 3 cv's per coastal edge would be better as well.
Either way, I would have to agree that a little rework for it is in order.
