Well, my no-food macro for 40-durab items works fine with just about anything...

But to be frank, what you asked for here is overly idealistic. If you have crafted i320 gear with different classes, you will see that even that alone will forces some classes to remove some very basic cross class skills. For instance, when I did i320 on my LTW, I had to remove Hasty Touch and CS II just to have enough room for Tricks, Comfort Zone, Blessing, PBP, Ingen1, Ingen2, Innovation, SH II, Maker's Mark and Flawless Syn. Well, we rarely use Hasty anymore, but obviously CS II is something that we use a lot in almost anything, whereas Ingen1 is something we don't usually use. At the end, the one skill that I really didn't use in crafting i320 in LTW turned out to be the Blessing, which is quite ironic. I ended up using the Miracle+Brow approach as mentioned in another thread on this forum. Anyway, my point is, after i320 on LTW, it is almost necessary to temper with the cross class panel to get back to normal state.
Muscle Memory is a skill that we used on almost anything prior the emergence of i320 gear. All my macros that deal with level 70 items needed it. Yet, for i320, we don't use MuMe at all... So again, it's hard to not switch cross class skills.
