Like being said before, just if you want to roleplay, otherwise i dont think it will be much better and not worth the money.
If you intend to roleplay however some things just to start. The problem you said with the names, even if it include stupid ones arent really a problem because for roleplay almost everyone uses an addon called TRP where you can give yourself an in character name, which would be the one that people see and speak to you with.
Second thing if you want to rp a worgen these guys might interest you:
Also dont mind the whole character on both sides thing, it would be wise to have one char to concentrate on, so they can have some ic progression in time, but thats just my opinion. The whole faction hating eachother is just fun sh1ttalk that is only ic. Speaking of the mighty horde and your even mightyer Tauren:
and last but not least if you want to rp your dk there are these cool (get it…) guys:
just by reading those you should get an idea if the rp here interests you or not. If it does, welcome! Happy to have you here! If not i would either look for another server or just wait two weeks for the content update because i think then you will find people for at least a short time on every server again.
