after watching this how can you say KT needs buff?

Did you actually watch the video? Or did you just randomly choose a video in which someone used a King Tiger and coincidentally also won the game? Throughout the 25 mins it was on the field, the point was proven repeatedly that its scatter is/was horrendous. The KT spent numerous shots shooting the dirt, sometimes getting 0 models even at 10 range and stationary. It took forever to vet up even with HEAT rounds and Panzer Commander and constant sturmpio support. I watched it for more than 30 mins and it didn't wipe a single infantry squad. It never got a single one-shot decrew on any team weapon. His opponent didn't build a single tank destroyer until 20 mins after the KT was seen, and the first time he used the Firefly it was on its own at 20 range vs a vetted King Tiger.
And that's exactly the point - even in the hands of a player like Jove and with the right doctrine pick, AND with a passive opponent who didn't try to encircle/flank the KT with medium tanks OR try to build a tank destroyer to kite it at range, the KT achieved very little.
It won several 1v1 long-ranged fights against Cromwell and won a short range fight vs a Firefly, but that's something even a P4 can do. Not sure how winning a 20 range engagement vs a single vet 0 Firefly which didn't fire Tulips or trading max range stationary shots vs a single Cromwell is indicative of anything.
Panzer Commander giving it arty made it able to counter AT guns, but that'd have been true with the Panther or P4 anyway.
