I'm going to guess that most people will suggest against grailing a unit that isn't 5*. And even then, only top tier 5* units that benefit from extra levels should be considered for grailing. i.e. I wouldn't consider grailing Waver, in spite of being S tier, simply because he is prized for his support abilites, not his stats.

Also, you need five grails to max out a 5* unit, whereas you need seven for a 4* unit. Keeping in mind, that grails are a VERY limited resource.

All that said, even though I'd suggest holding off for a 5* unit, Heracles is probably the best 4* to grail. He is future-proof and, being a DPS unit, benefits from the stats in leveling greatly.
