I just did some testing with Genesis on a variety of weapons. The weapons I used were in the Energy and Power Slots, being Ikelos_HC_V1.0.2, the Retraced Path trace rifle, the Heretic rocket launcher, and The Swarm machine gun. I wanted to confirm the second part of the Genesis perk: "Energy weapons regenerate ammo on hit when matching the damage type to the combatant's shields", if it worked on heavy weapons. In short, no. But I also noticed that this part was specific to "on hit" and when breaking the shield it did not regenerate any ammo even for Energy weapons. If Genesis could be reworked to regenerate ammo for all weapon types, including heavy, and to regenerate on matching shield break I think it would become more desirable now
