Uses for Lingering Smite & Greater Channel Smite?

[Wyrmfoe]

I am attempting to find uses for these two feats. I'm not concerned with critiquing them, as much as I truly hope to find some application for their powers.

However, I can't seem to envision when either is superior to just using the prerequisite Channel Smite itself.

I imagine Lingering Smite might provoke concentration checks each round, due to ongoing damage, but if the target is still up, wouldn't I be attacking it anyway (and thus forcing the same checks)? While the damage buff is (d6s to d8s), spreading the damage over as many rounds seems less helpful than a single blast at full strength. While damage-over-time is helpful in games like World of Warcraft, I'm not certain I see how such is useful in Pathfinder.

Likewise, Greater Channel Smite splits up my channel damage for each of my iterative attacks. The only use I currently see is to let each attack hopefully bypass particularly high damage reduction. However, if that was the case, wouldn't I still be better off with one large blast on my first attack? Is the presumption that, since missed attacks don't count against the pool, should the first attack fail due to some unforeseen power I can still benefit from the damage boost on following attacks?

I understand there is a sizable population that do not like these feats at all, perhaps for the above reasons. Acknowledging that from the onset, are there any uses for the above that might overcome these alleged deficiencies?

They are just bad feats. Also, as channel smite damage is either positive or negative energy, it doesn't help with DR, it automatically bypasses any DR.

Hey, call them Anti-feats with prerequisites.

Greater Channel Smite could be useful if you otherwise had access to the information regarding the HP status of your opponents, enabling you to play the RNG enough to maximize your potential damage against multiple opponents and not wasting would-be extraneous damage dice on a single target, but rather allowing you to allocate them on multiple attacks reaching multiple targets.

Admittedly better on reach and ranged builds, but it has at least that one niche.

[Driver_325yards]

Can't use it on range builds and there is no feat that allows you to know the HP status of your opponents. Further, even if you knew the hitpoint status of your opponents, that info would not be helpful given that the final damage is subject to the roll of the "channeling" die and to the saving throw of the target.

There is no niche. They are just horrible horrible feats. If you gave these feats away for free, they would literally add nothing to the character's powers other than futile options.

The Blood reader slayer talent will tell you exactly how many hps a target has. The feats still suck though, even if you have access to it. (a sanctified slayer with channeling scourge perhaps)

Is there a use for Lingering Smite that we might be overlooking? How is it particularly helpful versus the undead?
