I'd like to see Guild Points requirements get an update. The main problem with some crafts is that it takes a very long time to save up enough points to buy a Key Item or piece of rare/ex equipment.
SE did update this a while ago, to include food like Balik sis as a GP item, but more of a change is needed. The list of items required each day could benefit from an update, either boosting the GP you get or changing the item completely.
For example, for Journeyman fishing GP right now, it's 43 Crayfish for 1280 GP. Other comparable days are 43 Roasted corn for 1280 cooking GP, 22 Bronze swords for 1440 smithing GP and so on. In contrast, Apprentice gold GP is 2 Bucklers for 6420 GP.
I know there's a pattern each day, depending on your skill level, but I'm not sure how the GP amount is worked out, whether it's cost/rarity of materials or such. Perhaps something can be worked out to help people. Especially since traditional crafting is becoming harder lately with the existence of Synergy and only certain things selling in each craft.
