Hold on I am laughing really hard right now at some of the comments.
This game is how many years old? If some of you enjoyed leveling so much, You should have a ton of max level chars. Taking extra time to kill mobs, on content you already done so many times. Are you mental? Taking longer to do things is more fun?
If there was risk of dying, or if it was more rewarding for the work you did. I could understand, but to say clearly that taking more time to kill mobs is more fun for you, I question it. In fact, I am calling you out on lying.
What it really is, that most of the people who enjoy this. Have max level chars filled on the server, and don't want to level again... but they enjoy it being tedious for others, because that is the type of community wow has.
That makes more sense than a bunch of morons telling me this is a better system, when all it did was make things take longer and no risk at all.
