I don't think this weapon is as bad as everyone acts like it is. But admittedly, it's a little lackluster for an exotic, so here are a couple of changes I think it could do well with. Firstly, by activating the perk that refills the magazine, you should be able to overfill it. For example, if I fire a grenade and damage 3 enemies with it, and then quickly switch to an auto rifle and finish them off, Fighting Lion's magazine should then have 3 grenades in it, rather than just 1. And I think it should be possible to get the magazine up to 5 rounds with this method. The second change is more to do with consistency. I'm not exactly sure if direct, instant kills with Fighting Lion are supposed to immediately refill the magazine or not, because sometimes they do, and sometimes they don't. I believe they always should. A direct hit that results in a kill should always immediately put one round back in the magazine.
