DSM I don't think you're acknowledging that most people (including me) are taking into account that there's a miniscule chance of getting the ring while leveling in LoIO when we say it's a good idea.
I see two options for a charming druid 19-22: EK or LoIO. EK is the best because it's conveniently located, is outdoors with wide open spaces, has a convenient zoneline, a friendly guard, and has a ton of charmable mobs. LoIO is harder to get to but comes with a <1% chance of getting one of the most transformative items for a low-level charming druid that will be otherwise out of reach until the 40s or 50s.
If you're rolling a druid and you want to "be doing as much charm killing as [you] can", you can go to EK for the easiest, most convenient introduction to druid charming. Or if you don't mind the
downsides I mentioned earlier and want a lottery ticket for a goblin ring, you can go to LoIO.
If you disagree with that recommendation, what's your alternative and what's your argument for it?
