Fresh-Blooded Principles in Wicked

Wicked is known for its multiple reuses of cast members and it's really annoying me (I've ranted about this on Twitter to no end) and I figured why not take a look at just how recently there has been fresh blooded character in each of the current productions of Wicked (Minus the 2nd UK Tour because there has been no cast change yet.*) Now, my definition of a fresh-blooded principle is one that has never been in any production before and has not been the understudy or the standby prior to being a principle. I've listed the dates that they have been in the show and that includes any vacations or medical leaves.
If a person's name is underlined that means they are currently in the show

I find it strange how the West End along with the 2nd US Tour are the only companies that currently have fresh-blooded principles. Maybe it's just because I'm weird, but that really bothers me. ESPECIALLY the fact that it has been over 4 years since Broadway or the West End have had a fresh-blooded Elphaba! If the next cast changes coming up do not have some fresh blooded people I will scream!

*The 2nd UK Tour opened November 2017 and still features the original cast of that tour. However, a majority of its principal cast was transferred over from the international tour or from the previous UK Tour. The only fresh blooded principles were Aaron Sidwell as Fiyero and Amy Ross as Elphaba. (Whom I love!)
