If in the combat calculator there is no aspect of the equation where escorts reduce the chance of sinking an MM then this is contrary to the manual (p.22 & p.83).ORIGINAL: Harrybanana
If by "your convoys will be more vulnerable" you mean that an unescorted convoy will suffer more losses than an escorted convoy than I don't think that is true. Unless a change has been made that I am unaware of, escorts have no effect on how many MS are sunk.
Alvaro posted a few months ago that escorts did not reduce the chance of sinking MMs. If this has been changed than that is great, but I don't think it has been changed.
