As you can see, using its incarnon mode STILL isn't worth it. The change made it less bad, and the proposed change would have made it even less bad, but they implemented a change from 500->600 damage per shot rather than 600->700, or, I guess, 500->700. 700 damage per shot still wouldn't make it be better, but it would be something.
An unmodded comparison IS STILL RELEVANT, because in all cases, both modes will have the same mods, and the only mods the Incarnon form benefits more from than the normal mode are crit mods. But because Felarx has Devastating Attrition as a disincentive to use crits and doesn't have another comparable fifth evolution modifier, crits are still not worth it.
