probably backastrophe because you hit 2 columns instead of one like backstab skill
backastrophe is the worst. all abilities chargin either with weapon or cast and using the other to realease are underpowered as u either deal no dmg by charging or by releasing. (this might change with a much higher charge rate in further updates of the game)
as a melee go with backstab + powerstrike for solo or + knockdown for multiplayer and as a caster with the mage abilities.
