I think it’s pretty safe to assume we won’t see a new Mythic for Karakoth so soon, so your investiments won’t be in vain. Also, there is literally nothing else to do with the orbs right now that you couldn’t do with enough time.
The period of months in RED is roughly what could be an acceptable (?) time to craft an Orb of Power. The GREEN arrows/pyramids would be (single) cards you could use said Orbs to fully upgrade then, but in theory they can all be upgraded in the same month they are released using normal resources even commom cards if you use enough gold keys and gold.
So, what’s the point of using orbs if not for crafting Zuul anyway? You are not missing anything.
The little BLUE squares are threads where we’ll argue over silly things on each month. Each square is the equivalent of ten threads.
Jokes aside, my point is: To a certain degree some things won’t matter when you consider the timeframe as a whole, they only seems to matter if you look at things with an immediatist perspective.
