Only the X1 bosses have the extra help feature. It was a new feature brought in last event. Typical bosses such as Level 3 Whelljack or Level 2 Ratchet use the normal style help request, only sent out to a handful of players. The X1 bosses have made typical bosses seemingly impossible to defeat since you lose the guaranteed to be finished feature. Just saw a Level 6 and Level 5 Ratchet go unfinished with neither getting 20% damage.
