A few things I've seen researching this boss.
Use 2 tanks and 2 healers (if 3 healing) for pheromones. Or 2 tanks, 1 heal, one ranged dps if not.
Tanks can kite and stay at max distance so not to swap pheromones and still get the swipe.
Melee only on legs, ranged on body and legs when they come into range, moving is a dps loss. Multi-dotting legs can help melee if they can't keep up.
Keeping ranged and heals in the middle-ish should thought out any range issues.
Lust at start and get inside legs as we were for fast nuke to slow the boss down.
