I agree with the original poster, if your lucky enough to have an ls where people help each other the gaining of seals will be easy enough, but if like many of us when you ask in ls if anyone wants to go farming seals you get met with silence then your prety much screwed.
There needs to be a better solo option, take weapon trials, some weapons require you to kill like 6000 mobs+ to get the multi hit weapon but many of us are fine with that because we can solo it.

Most people don't want it easy they just want a solo option, make it 1000 mobs per seal and allot of us would jump at it.
