I remember Mono whips as far back as 2e (not sure if they were in 1e... can't remember)
They have always been incredibly dangerous weapons (both for operator and target!).
and it is that investment in skill VS the supreme damage they can dish out that makes them a possibly viable weapon.. if you accept the risks.
remember, no matter your strength, they are an 12p -8 AP attack! you need a strength of 11 to match that output with a combat axe! Meaning, now the human with a 2 STR is just as deadly as that troll with 10STR and an combat axe (only 10, not 11 due to the trolls +1 reach)
So that troll has spent 5 attribute points + Armed Combat skill points +$4000 to be as "effective" * While that human spent 1 attribute point + exotic weapon skill points +$10,000. And the Human still have the accuracy advantage!
*Couse that troll doesn't need to worry about cutting off his own hand, arm or head! .... unless his GM is a total dick on Critical glitches
