I noticed something on H Malk attempts last night that could be useful knowledge. I noticed on two separate occasions that when I was moving and got targeted by that thing that shoots me up in the air and spawns an add, I didn't get shot up in the air. The add still spawned, but I just kept moving as normal and avoided the damage or being flung up.
Now, of course, this isn't a make or break thing since movement will be restricted by orbs and if you disengage the landing then damage isn't a huge deal to manage. However, since we've been two healing it, I find that any avoidable damage makes a huge difference in my own survivability.
