Xar, it's a little over the line for you to arbitrarily call everyone lazy who used Zolo. Using the most efficient means possible to level is a far cry from being lazy--It's being smart. We reward that in every aspect of society.

On topic: I think, if anything, them not changing all similarly designed summoned mobs to only giving 1xp is a sign that they don't care. It wouldn't have taken that much longer to get'em all. In any case, until they make a post or something saying that they consider using similar mechanics then I don't think it's against the ToS.
