Heyo,

Yea, freezing level as zolw said really depends if you can manage in your sage to acquire the top spot refines. You gonna check your cluster and your sage and see how many players are advancing on the first ranks and additionally, their power to see if you'll have a chance to obtain the refines from it.

Refines from sage are really a great income and now that you got some more sources of getting them (Monthly shop, group shop, grocery shop f.e.) you'll be ale to max a refinement level in a very short time. Make sure to check yourself your cluster, which players are freezing and their power before you decide and if you need anything else feel free to let me know.

You're welcome
