Maybe it's a normal beam. Don't forget, Freeza is very powerful in that saga. Until.... Goku reached SSJ.
And Hibiki, a few words. " That's life " in the game everybody complains about a character's attack in the game. Freeza is one of those villians with nasty attacks. If you get hit by the ball, bad luck for you. Either keep a good eye open or you will be hit and slaughtered by the attack, thats life, no??..... The Kienzan is very cheap, but those dumb people doesn't even dodge it when it comes flying right towards them. It's SO easy to spot and yet SO easy to dodge.
And I'm going to mention this again: ESF is a mod, the attacks are modified to balance the game. If you call a Kienzan cheap, try the Kamehemaha or Gohan's Kamehemaha for size. Even the Transformation PL of Trunks and Gohan is highly exeggerated.
