That's the Level separation for formulas.
We all know that, right?
Let's see now,
Beginner has 2 tiers, Tier 1 and Tier 2, and accepts 1 tech slot for each of its tiers. Correct? Yes
Journeyman has also 2 tiers, Tier 3 and Tier 4, and accepts 2 tech slots. Correct? Yes
Expert brings in the change. It only has 1 tier, Tier 5, and it accepts 3 tech slots. Correct? Yes
Master, also has one tier, Tier 6, and it accepts 4 tech slots. Correct? Erm... Uh... Aaa. No? Why not?
At least that is the normal progression. That should be it.
Each Level brings in another tech slot.
But it is not implemented this way for T6
Now T6 are crippled to only 3 tech sockets. Why is that?
Why the current T6 tools have only 3 tech slots and are treated like they're part of the Expert Level instead being true Master formulas?
Why do we have to pay premium for Master formulas when we only receive Expert benefits?
Can the design team revise the current "crippled" T6 tier and bring it back into the Master level?
