I love Brock, and I'm not going to go into his career choices because that's a long debate
I agree that there are other people who needed it more, but at the same time, they built it up to such a degree that there was virtually no-one with the credibility to take the streak. Although weirdly, Taker beat Triple H, Brock once lost to Triple H, and Brock beat Taker.
And amusingly, WWE is probably so gunshy on putting the streak onto a new wrestler BECAUSE of Brock leaving originally.
I enjoyed the Wyatts at first, now I'm just enjoying their popularity and the decent quality wrestling they're putting on.
