I'm kinda agreeing with Endurell here, There are so many elements taken out of the conquest mode that, by rights, really belong there.
Petroglyph seem genuine with regards to customer feedback and acting on it. If there is a big enough call for any changes to be made, then perhaps they will go that extra mile and make them.
My suggestion? Wait for the game to come out, play it, then make up your minds what suits the game best. Also don't forget the conquest is only one mode of play, there is still the skirmish.
