I made a post about this a few days ago but it got little traction. With the arrival of Lightfall Fighting Lion's catalyst trait Chimera will not function under any circumstances. Before it would trigger upon shooting Fighting Lion then switching to another weapon, but now it no longer functions whatsoever, which makes the weapon feel clunky and slow. Please fix this Bungie or at least let us know you're looking into it, the best gun in the game deserves better.
