“Anywhere” is meant to say “Anywhere that isn’t on a unit or feature”.
Your take is basically correct in play though and a bit easier: If you pop it on a feature, it’s now a terrain objective.
Brawler mobs specifically are actually 4 or 5 points over-costed.
I have some planned tweaks for the formula, since it ended up being a little bit too hand-wavy as it stands now.
