Hate to tell you but as someone who was pre alpha testing Wildstar, their graphics blew chunks at this stage too. All games do. Being 'pretty' is not what you go for in the beginning. It's what you do at the end after you have everything else in place. Considering how things look at this stage for Pantheon, they are well on their way. More polish will come later.
And there really wasn't anything "hardcore" about Wildstar. We leveled to cap and were raiding in under a week. The only thing that said "hardcore" about that game was the original 40 man raids which they quickly gave up on opting for a more wow-esque approach with the more casual friendly side being pushed hard while nerfs destroyed the only good things about the game.
