LOL this. Pershing's HVAP ability "skillshot" sucks so bad I. Firefly's Tulips are actually useful. I use the Pershing all the time because it's a great unit but the only thing that HVAP ability has gotten me is a destroyed Pershing since a Tiger can get off what seems like an additional 2-3 shots before it fires (then misses!).
It used to ignore reload, allowing the Pershing to pull off a double tap.
Now though, its main use is sniping through shotblockers. It goes through anything like the special Jagdtiger, 17 pounder or Pak 43 rounds.
