I solo'd it yesterday w a WoR Warlock. Glass is not the problem. Your playstyle is. To help you out, here are a few tips: - Teir 1 is 650 power - Know the spawns - Telesto is the Besto - Hammerhead w Rampage - Blastfurnace w Rampage or something w precision range like a good scout rifle - Know the tuck away areas on the map (there are several) - have your gear set up correctly...running a hammer Titan with void gauntlets is probably not your best combo (hammers w armentarium works really well) - use a tether hunter. - Patience and Forethought is key The point is that there are several things you can do to avoid the Glass debuff. But running around like Helen Keller in a Boston Marathon is not one of them.
