Id say keep it just for the hell hunter race, this race is hard to play as it is, and sometimes only playable on few maps, reverting back would even "Nerf" it more as you would have to pick your nade spots even more carefully. Anyways, the fire nades or poison nades don't do any or very little damage, this is just another tactic IMO, same as molecule using his ulty on the bomb.

I know there is few issues with this, but honestly almost never anything major and very uncommon in general that, since hell hunter isn't used on every map.
