Well thats like saying to use a shotgun at long range. The melee button is a lead up to allow a single direct shot while lowering their shield a little, plus melee is best after it's Cybernetic buff and the shoulderpads. Only use meleewhen you have a good backup plan, yes I am telling you to "think" first, then use a more powerful weapon like a sniper or Shotgun. The SMG works but not so much. But yes moral of the story, only a fool uses "melee" on the Husk level, no I am not flaming just it's a hard lesson I see on all forums, everyone ALWAYS gets tempted to melee a husk! XDD
