I wouldnt be surprised if Cata classic comes out but I would be if it goes any further. If retail is any indication, people crave for flying and cataclysm was the expansion that opened it up nearly everywhere.
Transfer over what?
People also loved Mists. But it really depends on how long this game goes. I mean, weâre looking at around 6 years from now. So who knows what weâll get! 
Itâs only $15 to copy now.
Itâs free to go from Classic to BC or to stay in Classic. It only costs if you want your character in both versions.
What character?
I guess some confusion was introduced because I quoted the wrong dollar amount. I donât want to pay 40$ to be able to play just Burning Crusade.
So you are complaining and you donât even know what the process is?
You can either keep your character on Classic (for free), transfer your character to a BC server (also free), or pay a fee (apparently only $15 now) and have copies of your character on both Classic & BC servers.
My guess is theyâre talking about the boost because they donât want to level through the Vanilla zones.
I believe heâs stating he feels the boost @ $40.00 is what he doesnât want to pay. Just a miscommunication.
Okay, so I guess I need to say this straight forwardly - I didnât play Classic. I donât want to level through Vanilla. I just want to play Burning Crusade. The surveys they sent out talked about âfree character boostsâ. That never materialized because I guess they realized they could make big $$$ of those boosts unfortunately.
As I said, I enjoy BC but if I canât just play what I want to play, Iâm not going to be price-gouged by Blizzard. Still will remain in my heart my favorite expansion but Iâm not going to jump through hoops, either in terms of money or time (and time is money) just to be able to engage content I engaged more than a decade ago.
That was my initial hope when they announced Classic too, but based on the way that things have gone so far, I just donât see them going out on a limb like that.
'Twould be nice to see them attempt something like that though, imo.
Then donât play?
I really want Wrath or MOP back but BC so far is better than BFA *played classic more than I could stand it and only subbed up for classic when they announced BC (didnât buy SL) and I did play BC and Vanilla the first time around too and still find it more interesting (technically itâs still classic with BC talents and races the portal has not opened yet)
There were a lot of requests for BC and/or Classic+. I transferred over my Warrior for Classic, and will likely transfer her to Wrath eventually too. Also leveling a Hunter during the prepatch while I wait on 9.1.
Any character. If you have one on Classic right now, the first time you log in, youâll be given a choice to be on BC servers or move to Classic servers. Thatâs free. Even for new characters.
If you want to boost to 59 (which you can only do once), you pay $35.
If you want your character on both Classic and BC servers, you pay $15 to clone.
Obviously folks do. I mean BC private servers still pop up all the time. Heck Legion private servers are now a thing. Google has been known to be wrong on occasion though 
This is true. And yes, it sucks. Especially since itâs only one boost that you can have. But I guess there was also enough outrage over the boosts that they made this decision, as well.
People are still screaming that you can boost at all.
Yeah, this is correct. There was a vocal group of people calling for TBC.
Itâs a fun experience, and itâs free so people should give it a shot.
Iâm not going to.
My point though is moreso in saying âJust because I wonât play BCC doesnât mean I didnât want BC backâ. I just donât like the way theyâre implementing/monetizing it.
To be fair, it could be worse. It could be infinite boosts.
Look at it more like a server transfer. The monetization model isnât really different from Blizzards other services.
