If anyone needs a decent labyrinth team, this is running 35-45s avg, using toons for achievements, so maybe room for improvement:

Fallen Icarus Ed - nav+nav cos+sulpher or libra
Redan - Apoc/Bespoke
Wrathchild - Sacred/Nav/t3 Ascension or other high power cosmic
Osiris - rag/blight (had gun ghost with rag/redemption, same times)
