Bull's Charge - Make it not a stance, allow you to use attack skill, but you take double damage. This way, if you want to IAS with it, your choices are are limited because x4 damage with Frenzy.
Preservation- Make it target only allies less that 80% health. That way, it may not heal the right targets, but can really take the pressure off.
Charge- Make it maintainable with 12 Tactics (ONLY IN PVE)
Quick Shot - Make it unblock able for quick poison spreading
Plague Signet- Tone done the condition extension, and make it affect foes in the area.
Mind Burn - Make it an elite Rodgorts's Invocation. Up the energy to 10, give it a 5 second recharge, and make it do 100 damage and 3 seconds of Burning in the area.
Any suggestions?
