I think when content is brand new, it feels harder. When you have more people rerunning content with newer players, it's feels easier since the players who ran it before already knows what to do under certain situations, even if they don't mention it. The Burn was easy except the last boss the first day it came out, and my party wiped 3 times before we understood what we had to do for each situation (ie. if someone got frozen, or the aoe markers and predicting where to stand to avoid getting hit). So I just think it's all about more people just getting used to them.

Though I do admit it does feel like there is more DPS check in all SB content other than just raids than compared to the past.
