Which waystones are more important to use?

[BENJY]

i've been saving T15s with high rarity and instilling+corrupting them but im not sure if i should use corrupted T16 (no rarity) or T15 with high rarity on 4+ nodes in maps

i watched some videos on mapping, but since im playing in SSF, i cant juice out all of my waystones. im curious how others in a similar situation prefer to map or get better gear with limited resources. i'm just trying to complete my atlas by farming more splinters, any input would be great

I use t16 maps on+2 maps so that i can do t18 lvl82 maps. Gives best experience and loot.
