While it does make things interesting (NA here) it seems that either one team will reach the flag first and lock it down.
Or that one team will reach it first, have half the team stay, while the rest charge and get steamrolled by the entire enemy team and then the remaining half suffers the same.
EDIT: I doubt flags were ever meant to be placed evenly, by the time flags come it is usually just somone delaying while the entire remaining players are scattered throughout the whole map.
tl;dr: Flags uneven, can be completely one sided when they appear on new map.
