"Immolated" on monsters ends too quickly

“Enemies hit by Sacrifice are Immolated, causing them to take 100% more damage from your Pets.” It looks like the double damage boost lasts on monsters for only 5 seconds after the sacrifice damage. Gargantuans are very difficult to control and it would be great to increase the duration of this debuff to 30 seconds.
p.s. it would be nice to teleport Gargantuans there when using Piranhas
