I have bought it but when i have had time, i was busy on Cele with my friends (who do not really want to play on Lakeshire themselves… they only stayed back then due to the german RP-PVE. And they are > 60, they don´t speak english, there is also no realm left for them)
And IF you play both and do not log in for a time you are punished, because “there was no logging activity on the classic realms, what a pitty…” 
Yes if you do not like any changes, that´s bad…
IMHO those changes make sense.
And at one point, the “original” WoW made errors - the subs dropped back then.
It would make sense to try to learn from previous mistakes, as they clearly try, like the battleground changes
It´s not smart to redo old mistakes 
so, now i am stuck (or would be stuck) on your realm, and you are gone.
As I said, we will relay on the blue thread forever 
I think the best case we can hope for is, that they throw again all RP Realms together (And in my case, leave Celebras and throw the others on Cele)
But given the fact they do the same as they did in TBCC, with transfers off to two target realms, i am sceptical.
Yes, if they kill era Cele too, i am gone.
