These were VERY strong in the beginning of the season, and provided a huge advantage at SOTW. However, at this point in the season, I don't find them to be very useful (this perspective is probably fairly skewed, since I don't care much about money) unless you are aiming for something specifically (like the legendary set). So I do feel like it was very P2W initially, though I now feel their effects have "died off" a bit as the season has progressed.
