Felguard Intercept: Its tempting to leave this on auto-cast for quick closing at the start of a fight, but midway through the fight the pet will attempt to use the ability again. Since the ability has a minimum range this will require targeting a mob that it isn't currently attacking, charging off in the middle of a fight. What mob will possibly be in combat yet not within 8 yards of the tank?
A feared target of course, which doesn't count as CCed. And its likely sitting next to a sheep or other break-on-damage CC which will release when the felguard cleaves this new target. Thats right... the felguard on Defensive will actually peel off to a new target it has charged on its own initiative. It will do this on CCed targets even while on Passive.
Imp Burning Ember effect: This problem is a result of the combined interaction of a talent, pet AI, mob AI, and pet design. A destruction warlock will have the talent "Burning Embers" which puts up a DoT which ticks for 15% of the damage of a Soul Fire or Im's Fire Bolt; obviously this mainly serves to add a DoT effect to your Imp's attacks. However this puts the Imp into the worst possible position for a pet with regard to CC.
This talent turns the Imp into a ranged pet with a cast direct damage spell and 7 second DoT. Lets say there are multiple ranged targets CCed with something that breaks on damage, and the CC drops long enough for the target to let off an instant AoE before the CC is applied once more. A normal melee pet on defensive would immediately target the mob, take a few steps toward it, and then ignore the target once the new CC effect was applied. The Imp on the other hand would immediately start casting against the new threat and completely ignore the CC effect going up. Stop casting? Nah, just fire that shot and break that CC like a champ! Not only that but it now has a 7 second DoT applied preventing it from being controlled again.
DoTs being applied by pets is an undesirable aspect with regard to CC, but one that I think is necessary for variety in the game. However I don't think that it is necessary for a ranged pet which makes it all the harder to control. At the very least this decision should be available to hunters rather than to warlocks which are nearly forced to use a specific pet for a given spec. I also don't think that the control of a caster-pet provided by the AI is adequate considering the repercussions to mob control.
