Solo and a Bajillion Arbalests help

I’m really loving the difficulty of this raid. For once I’m struggling. Mayhem 4 is a little too bullet spongey for me, but that’s okay because the m3 raid solo is more challenging than I thought it would be. I died once to the valks, but otherwise I have had no troubles. Now I’m at Wotan and after he recharges his shield about a bajillion arbalests and centurions show up. I’m playing fl4k, can anyone give me advice on what to use or some sort of strategy for dealing with them, because i hate dying and having to run through 15 minutes of enemies.
