For new players - and the high percentage of max-level players who like to start new characters to try out the game's enthralling selection of classes - that initial rush now never stops. If you make use of Blizzard's masterstroke innovation and keep your character "rested" - allowing you to level at twice the speed if you play less, provided you log out in an inn or capital city - you can make a new level every time you turn the game on and play for a couple of hours, right the way up to level 40.
