Listen, anyone in the community could tell you that these bounties are ridiculously difficult to accomplish, even with a full suite of Solar 3.0 mods. Enemies that get Ignited usually are not killed by the Ignition itself, and that doesn't count for the bounty. The effort/reward ratio is BS on these bounties, so they either need to be adjusted to count for enemies that were Ignited while they died, or just taken out of the game.
