Entice would not be very useful to today's parties in Abyssea, where multiple enemies are pulled all the time. People would rather have a bunch of enemies slept and ready to be killed, so pulling one at a time is inefficient in the area you seem to be expressing concern about.

Notice the level for obtaining Entice: 10 ... this is mainly for party use, outside of Abyssea, pulling in places like Crawler's nest or anywhere else linking is an issue. It's true there are not many parties at low levels anymore, but there are still other uses for it.

Entice would also be useful when you want to solo enemies that link (anywhere in the game.)
