Here another great exemple of why the DPS most be reduced back to normal : I'm in a FFA match with excellent players : tmp, ak_rosh and overlord. I chose to sent my first units toward tmp we only lost a few units there and quickly both withdrawed when we realised we had both enough units to hurt too much.
ak_rosh did the same on his side and sent his units toward tmp as well. I realized it 3 minutes later when I saw that overlord's army was better then mine. It could only mean he didn't had to fight ak_rosh. Well... at that point the game was decided. By the time i could react to that reality and reorganize my defense on his side, He was right in the middle of my base exploding all my buildings in a matter of 30 seconds.
