Wargames, like Runoff, makes Minion Farming in the first minute almost impossible as they split up, but later on in the match Pilots get screwed over here. What tends to happen in the map is the eventually, one team will have more Titans. When that happens they tend to go either to the middle or to a team's "base". Once this happens, Pilots have no advantage. They don't have anywhere to run after a Rodeo, and if they don't try to fight back, it just so happens that Titans can crouch down and fire Cluster Missiles at many Minions. Think of Wargames like Training Grounds, except much smaller.
However, where Wargames shines is when both teams have Titans, which is usually the case. The pit in the middle does tend to force Titans to the "bases" which also means all Titans tend to fight in the same area. This calls for a lot more teamwork than usual (though not as much as Runoff) -- put simply, Wargames compliments LTS more than any other mode.
