Okay, I agree with the rest regarding stats and skills. Without knowing what you are truly planning on taking on (PvP, PvE, farming, etc.), its hard to advise you what to bring.
However, you stated that you want to keep your equipment and your attributes as is. The only thing you want to know is your skill setting.
I've never tried this, so if someone can correct me on this that would be great. If it works, then use Balanced Stance + Desparation Blow. With desparation blow you deal +10-34 damage and inflict a condition. But you fall down. Balance stance for 8 - 18 seconds, you can't be knocked down. If this works, then you can use Balance Stance then use Desparation Blow. Inflict damage and a condition and NOT be knocked down.
Personally, I'd get rid of Gladiator's Defense and replace it with 100 blades. Then use Watch Yourself for defense. Toss Shield stance and replace it with Riposte. Bring Parastic Bond and Insidious Parasite for healing. You can also bring mark of pain (because I don't think you do elemental damage).
So the skills I would have would be:
100 Blades (Elite) or Spiteful Spirit (Elite)
Riposte
Parasitic Bond
Insidious Parasite
Mark Of Pain (if you do only Physical Damage)
Enfeebling Blood (if you are vs warriors/rangers)/Faintheartedness
Distracting Blow
Healing Signet
Unless you want a really cheesey way of self heal, then use Grenth's Balance instead of 100 Blades. Just target the untouched foe and cast. Quick casting and gives you the difference between your health and the target. You gain a lot of health (if done correctly) and your target losses that much health.
100 Blades vs lots of melee types. Spiteful Spirit vs all others. The combination of mark of pain, enfeebling blood and insideious parasite spam plus 100 blades = massive damage and lots of health return when they attack. Riposte is good as a sweet defense as well.
Hope this helps.
