I completely agree with you, considering they're planning to increase allied seals with the daily marks that'll be a help. I think what they should do is make A rank mobs instead of a 3 hour possible respawn timer, make it more like 3 days, make the S ranks 7 days and leave the B ranks as is, that would turn people away from hunts and people would just happen upon them instead of groups hunting 24/7 around the clock for the A ranks. Take away the conditions for the S ranks and just put them on 7 day timer. Leave the windows in place as well, that way people don't know the exact time an A or S will spawn.
