With regard to weapons: Eclipse is a final multiplier. Roar is a faction modifier, additive with other faction modifiers. 30% eclipse is still stronger than 30% roar.
Nourish is still going to be overused, because it grants massive amounts of viral procs around you easily, on top of granting energy and elemental damage for weapons. It may have gotten lightly tapped, but it isn't going to stop people from using it or even impair said usage. They should remove the viral explosion entirely while they're at it. Also, if anyone gets upset about losing viral damage, consider how status weighting works...technically it might be a buff.
