To be fair, I think the person(s) in fee of Edge's persona building does not know what he/she/they are doing. They appear to have no idea what a wrestling "heel" is. They seem to suppose that as long as fans are disgusted then the nature is running. If you have in mind, my first query on Answers was once fairly equivalent to the one you might be asking right here. I were given a large number of solutions basically announcing "it's to build heat". For no matter faulty reasons, the WWE has became Edge into a whining, sniveling, crying, susceptible coward who has to be pressured to get in to the ring. When that does happen each match ends in but another run-in. Hell, he brings the "run-in" WITH HIM to the ring now. When is the closing time you saw Edge in reality win a match on his own? I don't have a problem with heels dishonest to win (I've been a Ric Flair fan for 33 years!) but Edge is NOT a excellent heel. If the reason for Edge's persona building IS to construct warmth they are going about it the unsuitable means. I don't think even the Undertaker taking all of those chair shots is serving to Edge get over. Edge has sunk so low that people are not "booing the bad guy", they're simply disgusted. Maybe Edge is not bodily succesful anymore of operating an entire fit so the WWE is diverting our consideration away from that by way of having run-ins in each and every Edge match? He IS quite restricted now in the quantity of strikes he does compared to only some years in the past.
