The current leashing behaviour is also extremely exploitable by ranged attackers. Before 1.18, people used it to solo Uraeus by repeatedly dotting it up, then making it return to its territory.

The zones in FFXIV are generally larger than in FFXI (a problem, I feel, as there is less diversity in the world) but some kind of endless tracking until the enemy loses sight/scent or a zone line is crossed would still work, I think.
