I think it all depends on what he values more, dragon stones or Elder Kais, and also what banners he's planning to summon on. If he already has a great box, it might be worth it to grind those 777 medals in 2-3 days, in order to use the Elder Kais on the great units he's already pulled. But if Elder Kais aren't his main priority, he might want to save those stones to summon on the next 120% lead banners...
