Just because you dont see evidence does not mean that it does not hurt at least some of them. I mean I could say that I never saw a newbie being kicked if they wanted to watch them thus this problem does not exist but that would be false since its only my subjective view of the things without knowing the whole deal.

What we do know as facts is: The MSQ roulette was created so that veterans will run these two dungeons for a bit of a reward so that newer people have the chance to finish this. The roulette would not have been necessary if the numbers would have been fine. Now we also know that after only two weeks after the change SE is not really happy with the rewards for this roulette (which again is there to have veterans run this) and plan to increase this. Why would they do that? Well the only good reason is because people do not run this enough for the current reward so they want to increase it to have more people running this. If less people are doing that this kinda implies that there will be some people that now have to wait longer than they did before the change thus its hurting them.

Next to these facts we also know from experience of other players and from countless of threads where newer people complained about the story (especially the one between ARR and HW) that not everyone is playing this for the story but those will now be forced to watch it..these players (who do exist) will be hurt. So the change hurts them too.

So in the end we might not now the true numbers but we know that certain people exit thus they will be hurt by this change and we also know that SE will increase the rewards which they only did before when there were not enough people running certain things. For me its quite logical that players are hurt by this and no personal experience in any way will change these facts. (And yes I dare to say that these are facts and not personal opinions)
