I know TKD would kill me by hearing this, but imo, i never saw Kane as a real wrestler.
Let me put it in this way, he is a monster, 7ft tall, 325lbs and played as a heel most of his career but now he looks as face?
I never saw him do any other finisher move than the chock slam, taker atleast as the Tombstone pile driver and the last ride not just the chock slam.
Yes Kane is so powerful, has more power than Taker, but he never really did many unique things in wrestling except for the Inferno match which is also not his own invention as WWE made that storyline of him being burned and his face was burned or something. So in my opinion he is just a bigger script or copy for the Undertaker, but didnt have his own style. I see him as a masked Taker nothing more.
sorry TDK
