Falcons loaded with these guys are great. I know most eldar generals like to use the tactic
of dropping these guys out of a falcon to toast someone who is bothering you. I love the smell of burnt Carnifex in the morning. I want to try a couple squads of these guys to take down a titan in apocalypse. I usually use the fire dragons with no exarch and 5-6 troops. Larger squads, or squads with exarchs usually don't make it to the enemy.
