I recently just played a game on slaughter mode where you had to kill the enemy demi god 30 times. I had great fun doing this until my side gained the upper hand (since I bought carapultasauri ) and we began to destroy our way through the enemys defences. The problem began here where all the AI reinforcements did was attack the indestructible fortress and ignore the enemy demigod. This meant the reinforcements kept piling up and up whilst attacking the fortress until there were so many the lag was overwhelming and I had to give up.

Its just a suggestion but there desperately needs to be something else for reinforcements to do in these kinds of gamememodes instead of just clumping together and lagging the game. Alternatively it would be good if some kind of unit cap is implemeted so that once so many AI reinforcements are on the field no more will spawn and this shopuld help reduce this "clumping" effect hopefully.
