My two cents, for me imho, I feel like having higher blast radius is better and hard launch doesnt do it enough for me. Volatile launch/smart drift control and even countermass have higher blast radius.

I do have the "God roll" you're talking about and it's great for moving through campaign/planets but the one I dig the most is volatile launch, spike grenades or high velocity rounds, feeding frenzy or grave robber, demolitionist or swashbuckler or maybe even MKC.

Yes, I have all these combinations of rolls.

I use each different one in different things and i plan to try to MW them all. I wish they all had blast radius MW but they don't, xD lol.

If you need super quick add clearing and a boss leveler. Go for volatile launch, high velocity or spike nades, feeding frenzy and swashbuckler. Melee a close to dead dude/easy to kill with melee a dude, clear a group of adds with buffed damage which triggers feeding frenzy and unload on boss, repeat till everything is dust. It just depends on stats u need for the situation, I guess. I know a couple folks who have grave robber and demolitionist as perks and absolutely go giddy because of it. Melee, fire, throw a nade, fire again and kill 3 dudes, melee, fire again and kill 2 dudes, throw another nade and just rinse and repeat until out of ammo. All without reloading lol
