I don't know how much they hit for. Can't say it's out of the realm of possibility. Super geared tanks can already survive blighted in T6 when moving. If it's a damage mechanic and not the flat 30k that SE likes to use for auto kill then people can out gear it.
They have like a super regen from what I hear so unless its HP are calculated from the source golems and it's on the last leg anyway, you just won't take it down.
