Well with the introduction of the new KCNM battles u can now aquire seals randomly in the coffers dropped after battle.

The new and upcoming update allows you to destroy chests for cruor so they are able to manipulate chests within abyssea so why not add seals into the chests from parties into abyssea that can be added to lots!! not frequent drops but fairly rare so not everyone has every job done in a day. would give people another way to aquire these seals which SE mentioned there would be new ways to get +1 and +2 items in the first abyssea areas ... they gave us the +2 but not the +1's. So i ma just throwing the idea out there as something that would help people get seals while xp'ing partying feet farming etc...

same as the bastion ops u could make the seals respective to the region head seals in attowha only feet seals in vunkrel only etc etc. just a thought.
