Not gonna bother replying to anyone but Callisto93, as the rest of you have only posted stupidity that doesn't deserve my time.
@Callisto, the issue here is that one day these challenge modes WILL be fixed. All that means is that new players get screwed over hard, while older players got to run through this without any work whatsoever. The fact is, when you saw someone with a CM transmog on retail, it meant something. It was a very rare occurrence. To put it into perspective, what you are saying is that rarity is not an issue for people. I completely disagree. Imagine if Ashes of Al'ar dropped 100%, or Invincible dropped 100%. Or hell, Astral Cloud Serpent had a 100% drop rate. Would those items be worth anything at that point?
Like Wolf mentioned, right now, there is no such thing as Challenge Modes. They are a complete husk of what they should be, merely heroics with a timer added that can be ignored completely since you have to be quite braindead to not make the timer.
Finally, it won't take long to introduce item scaling. Item scaling is already in effect in BGs (you're welcome to test). In fact, from staff replies, we can see they have already fixed item scaling now and it is only waiting to be applied. The reason item scaling wasn't put in effect before opening challenge modes, is because clearly our QA team failed to realise that ilvl scaling should be implemented for challenge modes.
No-one who has done the challenge modes deserves the rewards, period. In the matter of an hour, I managed to finish my last 3 challenge modes... one...hour... People who are arguing to keep their rewards are just another example of the entitlement attitude you see everywhere today. Just wanting free handouts while doing no work whatsoever for it. It's really quite pathetic in my opinion.
