I think the changes are very good in a balanced manner:
* It keeps the Open World, Social aspect (thank goodness it's not Instanced).
* Allows EVERY Player to do their own Daily Hunts and their own exclusive B Rank Weekly Mark (worth 50 Seals), solo, without any interruptions, at their own leisure.
* Big boost in Allied Seals for each individual player doing Daily Hunts and their own Weekly Mark.
* Still keeps the excitement of finding S Ranks and A Ranks in a group setting.
* It allows players who were getting "beaten out" to earn the nice Allied Seal Rewards even if they don't bother with A or S's.
Nice update. :)
