If they did decide to a conquest system (which I think is a good idea) I don't think it should be related to seals, there should be items similar to like in 11 based on a unique currency (conquest points again?) like 'Instant-Return' scrolls, exp rings etc.

Like i said, signet should have been permanent. There was no point for it not to be.
One way to do it could be having the signet effect permanent in that, you will always get conquest points for killing mobs but in order to get the buffs you could talk to an NPC to get an enhancement (these NPC's could be in town as well as camps) and possibly even choose duration.

i.e 200 conquest points for a 1 hour signet with 'refresh', 300 for 2 hour, 400 for 3 hour etc

This way people will always get points, but if people want they can choose to have a buff/multiple buffs and can also set their duration so that the need to return to town/a camp is minimal.
