I'm not familiar with rotations using the specialist skills, w.o those you definitely need cross class. Carpenter to 50 for Byregots Blessing, GSM to 54? For makers mark, alc 50 comfort zone, Arm 50 piece by piece, Weaver 50 careful sybth II.

Bsm and ltw aren't currently used in my 2-star rotations, but we're previously.
