Here is the problem with the AI. You put your pet to obey, it will only use 1 of its 4 skills, Wind Blade.
A good summoner will cast Bio/bio2/miasma/thunder and manually press contagion afterwards to prolong all 4 dots (use raging strikes before hand if available). Now, you pressed contagion on your pet, and now he is screwed up and will cast contagion on cooldown (not on command). So you press obey again afterwards, bit if there is an AOE need, your pet won't cast its 2nd aoe skill. So, you manually cast your pet aoe skill, and now your pet casts contagion automatically which can screw up your rotations with dots. To be honest, after playing WOW, one thing they did right was the pet system and pet management. I can't believe it even took SE 1 month to move summons skills off the GCD, which should have been done before the game's release, but they need to make pets actually intuitive like having each ability having an autocast toggle.
