Nonsense.
The effect would be the opposite. People that grind up to lvl 35 and who have all the looms they need mostly quit because they are bored.
And off course that people who made grind their way of life would be against it, I would expect nothing else.
But I believe that wipe would have opposite effect, and that people would return after the wipe and that new players would be encouraged.
How would that encourage new players? If they can do better, they'll have more fun of course.
But they won't plan for the long term since they know there will be a new wipe down the path. There will be little commitment to the game.
I am already bored, but I have alts to peasant around in. I think a better option for getting people more interested is to allow alts in Strategus again. That way they can feel that there's a point in making different characters and item sets for them as well, if they feel like they have achieved everything there is to achieve with their main character.
