Hi guys, im at work and i cant open any ff14 site except these,

could you guys give some pointers please.

Questions i got:
- on ilvl 90 gear (i.e. smn), what should i melt in? i know theres a cap but how does this cap work? I.e. if i put 3 x crit+9 in it, can i then also put 2 x i.e. 2x determin+6 in it?
Or is the cap based on total stats added?

- How does crit(rank4 is +9) work vs det (rank 4 is +6) is there a hard cap?

- Can i read about this or is there a straight anwser on how to materia for smn in ilvl 90 gear.

- Is there a budget way to do this?
