Exactly. I saw it could be broken in Crucible because of the 90% DR and the constant seeker units rushing someone at the same time, but a nerf across the board seems a bit much unlike how they nerfed Barrier and Bubble for Titan, but gave it DR in PvE so nothing changed for it. That sort of thing is why nerfing something in PvE just doesn't make sense in that way.
I have a tinfoil hat theory that it could be due to an upcoming synergy with a certain buffed solar special weapon that rhymes with sledge of smintent but like that’s it lol.(and that would only be the case if they gave it scorching projectiles from the bleak watcher which means insane uptime on weavewalk with dawn chorus equipped)
