@3, I almost forgot that one



,
Yeah we better not go there,
I am really after the most realistic max speed such a u-boat would have reached as I have already reduced the effects of the abilities and still get a 20knot at lvl 2 which IMHO is rubbish.
You know, they could have made this system work a treat e.g. have scaled random effects in there e.g. hit button meant faster speed and more fuel consumption but they should have added a 1-15% chance for a failure to occur causing minor damage etc.
Aw well never mind
