Missing Enchantment Selections?

On my blood dk, mr robot is constantly telling me to replace my Gift of Versatility (+100vers +2% speed) enchant with a +200 strength enchant. I’ve run sims on both and they come out the same (within margin of error) which would suggest the 2% runspeed which doesnt (i don’t think) get factored in would make the old enchant better right?

In any case, the versatility enchant isn’t even in the list of available enchantments.

I think we ignore the pre-Legion enchants for the most part, actually helps simplify and speed up the optimizer quite a bit in general, and they are very rarely used. If it ranks more or less the same, feel free to leave your current enchant though.
