I'd be willing to trade 10 or maybe even 15 yalms of it's huge 30y range to allow it to go through walls. It's extremely hard to get a halfway decent use of it in during Volcanic Heart map.

Alternatively or additionally, I'd love if it was changed to be a channeled effect around you so people who come into range later would also get the buff. For the record, this is how the Frontliner's march buff on BRD already works so it's kinda counterintuitive that the LB that even has the effect swirling around you is a snapshotted buff instead. Since your teammates already lose the buff if you die during it, making it a passively channeled one would give you a bit more leeway in where you're popping it to get some use out of it.

Either being blocked by walls needs to go or the LB being a onetime snapshot needs to go.

I think the buff effect itself is okay enough but I'd also consider if the strength of the effect is really strong enough to be held behind a 120 second charge timer.
