The levels have been flying by. I was questioning their level 80 cap, seemed pretty high for launch, and the original GW only went to level 20 so I thought it might not work for them. It was also a bit slow at the early levels, at least it felt that way because most games really fly through the first 10 levels. GW2 instead evenly paces all the levels, so going from 21 to 22 took about the same time as going from level 2 to 3. This really keeps the experience smooth, I don't feel any grinding at all.
