And they are more fragile than the event bosses.
I'm only nuking my own low level bosses and within 10 minutes before maintenance (did that once this morning though it was hardly needed). Over level 70 Seeds will be shared with allies to hopefully let a few people have a chance at getting a hit in for the daily quest.
