Anyone coming from WoW to CoX will surely agree that mods are a fantastic addition to the game.
You people who think otherwise need to realize that there is a big difference between 'mods' and 'hacks'.
A mod, something that improves your play without changing game mechanics, is a -good- thing. An in-game clock, for example. Or a more extensive friends list. WoW has literally hundreds of these, and they're fantastic.
Hacks are something totally different, and I think that's what most of you "Negative" people are trying to argue against. Make the distiction between the two, and I don't see how you can see Mods as a negative thing...
