Which is why I listed a few non-certain death ones. Roleblocker only kills him if they target the doctor, or they roleblock and kill the same person WITHOUT the doctor also targeting them. It also can take a while to find the right person to block. Day kill only works if you find one of the right people.
Also, a watcher, a sensor, a lie detector all can work. And that's just using what's in this list. Most people have to make decisions based upon no information anyway, the whole town does if the cop dies. You just have to figure out if someone needs lynched. Such as, anyone calling for mass claim is a good choice in this setup.
But all I'm trying to show is LRod can be used effectively as an auto, all you need to do is give people the right tools. Should it be used often? No. But then that's why it's in the uncommon roles section.
Related: Might want to break roles down more and make a rarely used section too. For roles that aren't bastard, but do require some thought when adding them to the mix.
