Sword of Spirit
Legend
Why do you feel this is a problem, or that it needs solving? Are you under the impression that there's a faction of WotC employees desperate that nobody refer to their baby as "5E"?
It'll be referred to as 5E by us. It'll just be "D&D" to those not already playing it and who don't care about previous editions
Pretty much what you said. The impression I get from the way Mike Mearls has consistently said he just wants it called D&D is that he doesn't want an edition number used. I guess it's the lifecoach and problem-solver in me, but when I see someone say they want one thing and act in a manner counterproductive to attaining it, I want to give them some useful advice.
I don't really have a problem with it being called 5e myself.
