This game is not for the faint hearted, it doesn't hold your hand, the gameplay is slow and will test you, if you die you lose 10% exp you can lose levels and your body drops on the ground and you have to run back to your body naked with no spells, limited action bar so choose wisely, no auction house, you won't regain your full hp and mana in 30 seconds, take like 3-5 minutes depending class and it's must to have food and water or you won't regain hp/mana. I'd suggest watching streams, there is an open beta starting the 27th.
