I did the math, and if you are able to get max points per day, it would take @21 days to get 100k guild points, and that's IF you can get all the ingrediants....cooking is by far the easiest so long as conquest areas are controlled....Fishing is another easy one to get the items for
I don't agree with lifting the cap entirely...raising it a bit wouldn't hurt, and a revision of the items needed would make it a tad easier for people to get GP, as well as help newer crafters to obtain points for their guild items
