Trapper (active during waves) --> 5x explosion, 5x gas, 4x thunder
Damage Tower Mage --> 6x longshot single
Aura Monk --> 4x weaken
Waller Warrior --> 9x walls

Each lane is covered explosion+gas before the walls. Every oger-lane has additionally a thunder trap infront of the wall. The bottom-left lane has 3 longshots since most ogers come there. Every other choke point is addionally covered by 1 longshot, which sit on a thunder trap. They treat the oger from east and the assassins. Please note that in my screenshot I placed one of the longshots not on the thunder trap. It should also sit on the thunder trap.
