forge of the ancients stack with dwarven hammer?

[Wish]

so by those standards what I had was 50 + 20 + 25 + 50...

I tested with the gatestone.... normally 65e/65s

after Ancients the gatestone would be 32/32
after the steel oven would make that 25/25
dwarven hammer reduces that by a quarter which is 18/18
forge lord should make that 9/9

but it was 6/6 -- so what happened i think was dwarven + forgerlord were counted as one calculation as 75% so 25/25 became 6/6 after the combined forge bonus.

it is praetorus and calmon who are right.
