S-Rank mobs needs a invulnerability buff on S-RANKs

[Conadrium]

Square Enix should just put a 10-minute invulnerability buff on all S rank.
Having a 5-10 minute invulnerability buff would not hurt anything.

10 minutes is way too long but 3 is fine. This is especially true about SS ranks when even people there killing minions might not make it in time for credit which is flatly ridiculous.

I don’t agree we should have to wait for people from other world servers.
