I might be the only one, or perhaps I'm just voicing the opinions of many but gather Clusters is the biggest pain in the world.

Shards and Crystals which do not have much of a limit for gathers and the fact I can send my retainers to go get them, Clusters require large amount of time to get. you can obtain 105 Clusters in an hour.

As a Culinary this is not enough especially for 3/4 star foods where I would burn through that in 10 minutes. Not only that I would technically need another 105 for the other half of shards so 2 hours total in Clusters. I'm not discounting the fact you have 6 different elements to get to, calculating it out at a maximum it would take

96 hours to gather 10k fire/ clusters
112 hours to gather the rest resulting in a total of 640 hours to max your clusters.

I would purpose for having the Cluster gathers be taken off the undiscovered nodes or increase the nodes spawn rates to one ever one or two in game hours.

So much time gathering them T.T
