You can take out a fort with 1 MOW and some good tactics but i would suggest taking at least 3 MOW's with maximum calibure mounted. If not MOW's then 3 class 1 ships. Cannons having a standard reload time would be unrealistic, the bigger the calibure the longer it would have taken to reload. Imagine having 1 12Ibs cannon, reloading pulling it back into firing position and firing it it. Then dowing the same with a 22Ibs cannon, and while you was doing this you was been timed. Cannons took less time to reload than culverines because they was smaller, to remain releasic it would be best to keep with the way we have it now, we can reduce reload times between calibures that would be fine by me. But we can't have all calibures or even any calibures share the same reload times.
