Not a huge number story but some interesting tactics:
Back on live a buddy and I made stalkers as our first villain characters. I went claws he went ninja blade. We developed a tactic where we would run at an enemy from opposite sides, jump over them and activate Focus or Soaring Dragon on alternating passes. We called it "Jousting" and we made many a boss flop around helplessly as we poked them.
Efficiency: Medium
Risk: Low
Fun factor: High
