Most of the energy-based Warrior attacks are lame. I'd personally want an interrupt such as Distracting Blow or Savage Slash, but otherwise adrenaline is where you want to be.
If you have high Tactics i usually throw in Soldiers Strike for a nice, spammable, unblockable energy based attack. Good to use as an opener and it gives you summut to use while your adrenaline is charging.
