This skills functionality serve no purpose whatsoever both in PVE and PVP. Here's a quick REAL balancing for Warlocks overall just with this skill being changed. Just remove the meaningless healing and make the skill usable while under any Crowd control ability or stunned. Will help Warlocks avoid getting instantly demolished by classes that can easily avoid the Warlocks Crowd control skills like BD, Druid, Barb etc, and give them a fighting chance.

Chop is already one of the weakest main DOT skills any class has, why increase its cooldown and not its damage when isn't the abilities main purpose to "Stack multiple Bleeds" on the enemy? This kinda counters the skills main functionality that makes it even a viable choice to even consider using during combat. When damage is certainly not its purpose because even at 5/5 its damage is near mediocre. Consider making this a non-mediocre bleed with an increased duration & cooldown of about 15sec, it would helps Barb's focus more on using other abilities rather than having to choose between skills like "Strong Blow" or "Chop" that have nearly identical cooldown times.

All healing Classes Need Heal nerf only in arena. A all +10 Shaman is OverPowered, a full +10 rogue or DK can't take a shaman +10 down because shaman heals more than the DK or Rogue basic attack. All heals in Arena must be nerf by 35%, A shaman can crit on those heals meaning he can heal up to 600hp with one tick which is ridiculous. Not to mention they can increase their defense and magic defense making them tank like defense.
