How are your skills relative to the person in the log?
How is the opponent's skills relative to the person in the log?
Look at the relative equipment of each party.

You can't replicate what you see in a log just by using the same commands, because a lot more goes into any PK encounter as you know. Logs provide some tactical insights, but you should not read them as a guide for how to be successful with that build since you don't have the relevant knowledge to be able to replicate those results most of the time.

I will also say, it probably takes a while for most of us to learn to PK decently with a class, and trial and error really is the best teacher in that regard. I did alright with Allysia because I have played bards pretty much more than any other class but warrior. I don't think people can look at logs of Allysia though and then roll w-elf nexus bard and expect to just dominate battleragers with the same ease even if it is a potent build. However, if I were in your cabal and you were playing w-elf bard, I'd be happy to suggest what works and how to get the most out of the build.

I have to think getting tips from people IC is much better than log reading, and trial and error also helps a lot.
