strat idea for hard mode gatekeeper section

Can't believe I didn't think of this earlier- we usually have problems defending the middle conflux after the relics are picked up because those minotaurs start spawning in the back and heading straight for it. How about a Titan with the ST 44 headpiece (which BLINDS enemies that walk through their bubble) run UP THE STAIRS TOWARDS THEM as they spawn and drop a bubble near the top of the stairs? That would buy you precious seconds to rocket them without them breathing down your neck.
