Retail is doing fine and has more players then classic wow

That wasn’t evidence of that.
You pulled out a segment of something that vaguely supported your argument, I added context because you lacked it.

As for whether or not they made smaller servers.

You need to PROVE that they made Classic servers the same size as retail or your argument is invalid.

When you make a claim, you need to provide evidence. So far, you haven’t.

As you are the originator of said claim, you need support.
