Returning Player

Hey guys,
I played on Wildhammer back in Vanilla/BC then took a hiatus from wow, playing maybe a month of each xpac until now . I’m sort of wanting to restart in the server I had originally started the grind. Is the server populated enough to enjoy at this point? I would probably be starting from level one again as I just leveled one horde and alliance to see both sides of the story before deciding this.
