Not sure how you can get confused over selecting your realm.
I don't think you understand the suggestion.
Those names you mentioned weren't for same thing. Feenix,name which has nothing to do with wow, is server that has 3 realms that are related to wow lore : Warsong, Al'Akir and Emerald Dream. Anyone who ever played private server for more than 2 years already knows the names of realms and what they stand for.
You can apply same logic for retail. When go and tell my friend I played on Twisting Nether he has no idea what that means. Same would be I told him I have 2 chars on Ravenholdt too.
If you don't play there, ofc you won't know anything about it. Both of those names are, ofc, wow realms with different label. Imagine if WoW named it's realms by WoW pvp, WoW pve, WoW pveRP. WoWpvpRP

Yea... we got only 2 realms here. But please don't be so skeptical about Nostalrius. Almost year after launch it shows no signs of slowing down. I meet new players every day and I yet have to see online count go below 4500.
They obviously have no permanent solution for these laggs which, lets be honest, slowly start to piss everyone off. It's not huge, but it sometimes happen just when it shouldn't and causes you trouble which can cost you even a dungeon wipe (my own experience, lagged out on 34ms and pulled extra pack of mobs).
Herb / Ore spawns are another issue where I can see the solution in opening another realm and allow transfers to maintain the rates and blizzlike feeling.
We could easily witness opening of another pvp realm by the end of first half of 2016 due to these reasons combined, so Nost having 2 realms now could be easily changed in future.
How would that new realm be named. Nostalrius Begins PvP 2 ? Cmon... you serious?

You can't be...

Without any solution to addon problems it takes less than 30mins to re-adjust stuff.
If that solution exists its even better. 5mins and get your settings back.
Why not? If that's gonna make Nostalrius look and feel more blizzlike, i'm all up for it.
