I'm pretty sure roads do provide a speed bonus, and apart from that roads are beneficial to vehicles because they provide a fast route unhampered by obstacles and changing terrain. Even without a speed bonus this is enough reason to want to use roads where possible.
I wouldn't play COH or COH2 if it weren't for the random factor. It's what keeps the game interesting. It's silly to say that games are decided by random factors - this is extremely rare, and thanks to the law of large numbers the meta always evens out to have the better players winning.
If I wanted to play a spreadsheet I would play Starcraft or one of the other yawnful RTS games that I have no interest in.
okay first of all don't use names publically. second there is an email somewhere.
What? Even when it's an obvious troll/griefer? People should know as to avoid these people. Also your answer of "there's an email somewhere" is about the least helpful response ever.
