I dont know how to beat them solo on TVHM. I play Gaige on lvl 52 but I do absolutely no damage to the dragons, even with 6000 x20 shotgun with 40% crit modifier. It looks like the raid boss scaling in TVHM is broken or something. Also the Shock dragon keep killing me with his neverending shock beam... On this video nothing like that happens. Is it really that big difference between normal and TVHM in Raid boss fight ?
