Sorry not looking in to your logs/situation too much. Just thought I’d describe how we do that specific section.
Same barrel order as you. We wait until around 40%, pop barrel and at that time icefall aim indicator should be down. There we decide on the lock portal depending on icefall.
If the icefall is not blocking our path to final barrel we will setup a portal to the middle of the room for our tank to use for avalanche. If it is blocking, the tank will have its own portal again but also we will setup another portal for the raid to jump across with, and that will be after the avalanche has stopped.
Broadsides here are always to the left to prevent blocking the raid. This is nowhere near the tank as he’s portaled to the middle of the room. Always try and break all barrels with broadsides with the second round of them (if that makes sense). That way you can concentrate on just keeping them out of the raid and tight for the remainder of the fight.
Main take away: use a portal to the middle of the room for tank to take avalanche away. We only used one lock so it’s deffo possible to put down tank portal, wait 10s for cd then portal for raid if needed. This should fix your issue with broadsiders getting hit by avalanche!
