No. There are plenty of MMORPG on PC, and most of the ones on console have the classes you speak of. If you wanted to play a standard(staple) MMORPG then you've plenty to choose from with various system requirements. Some like Tera even have skills and controls that are better used with a console controller but with the graphics/player base of a PC game. D1 Vanilla felt like an MMORPG spin-off of Halo(I say that after having played Halo avidly until Bungie gave whatever was left after Halo 4 to Microsoft, and D1 from release until D2), and I feel like D1 after HoW, as well as, D2 have tried hard to move away from that. That's why it's not a staple MMORPG, but it's not just an RPG FPS with matchmaking either. It's unique unto itself. I loved D1 because it wasn't like any other MMORPG that I'd played before, and I've played many Korean ones on PC. Personally, I'd hate to be locked into just a Cleric role again, even though I play a Hunter in D2. However, in staple MMORPG it's hard to find a capable tank/cleric and everything in any raid/dungeon/instance depends on them being good at their classes. I played a Cleric in the last PC MMORPG that I played because after waiting 7+ hours for a Cleric just to go to some crappy instance for the quest reward and still not getting to complete it. It wasn't a bad class, though it wasn't as easy as DPS(I'm only speaking of that one game, not making a statement that says all games DPS classes are super simple) and I was good at it, but at the end of the day I felt like I hadn't much choice if I ever wanted to go anywhere or get anything good in the game. All in all, it's good to not have to wait hours and hours to do an stupidly simple dungeon.
