And people enjoyed raiding more when they could actually get their BiS, so removing that was a really, really stupid decision from Blizzard. Its the same with every type of gaming, being awarded for doing is always better than being awarded with RNG. You could combine the two by having RNG via WF while being able to upgrade items so people eventually get their BiS, but no thats not the case - via lottery you can get BiS without ever doing any hard content whatsoever.
Current system is just horrible anyway you look at it and only people that "enjoy" it are those who "didn't care" in the first place and entitled brats. Its just that simple and one can only hope Blizzard gets their head out of that gigantic arse of theirs and actually makes the game good again.
