Not exactly, it first started off as head-shots in cod4; you completed your gun challenges to get easy xp. Then people discovered that domination had no time limit on a score limit and that you could continuously get 15 points per capture of a flag so both teams took it in turn capturing 1 flag which got up to 6,000 xp per match + match bonus. Also due to the lack of time limit you could just kill as much as you wanted so teams took it in turns killing each other to get any kill streak they could.
