Because people then have to see that maybe we were a bit right about it, maybe it will not be that worse then we thought it would be (but that is something we will see in the future) but it was at least enough that SE already decided to increase the reward. They never do these things just for fun. They gave us the clusters on top of the adventurer in need bonus because they saw that people still did not run it with certain jobs so they do change things when its not going as intended. And seeing how fast the change happened..well the numbers spoke for themselves.
And since they never raised these things before the change we can say that this was because of the recent change..so the change seems to have impacted the roulette enough that they saw it as necessary to increase the prices even more.
I am never going to use it because if I ever go back into this I will watch through that (and probably just do it if friends need to run it through) but how exactly can they punish people for that? DCs happen and since patch 4.2 Chaos data center for example is horrible at times..how will the GM decide that this was not an accident? I mean they dont take video or screenshots of botting as evidence..how will they use DC as one? They could only do something if someone wrote it down but who would be stupid enough to do that if they plan on using it?
