But..on the other hand I am almost positive the Devs are slowly working on the AI of pets. Some things have gotten better already. Just waiting also to see what will happen with some others, like the AI for the Magery Mastery and buffing enemies, and debuffing self..
The monster I am almost positive when the proper % life is left on it, can have a "flag" toggle. Make it 30%, or 20% whatever. Then increase the chance of the pet chaining WOD,s. For players the when you can cast WOD successfully, depends on the player's circle level also, i.e. when you can start doing well with 25% life of 30% enemy life. This could be solved several different ways and just make it for the pet that has 6th circle (full 120SW trained) to start "choosing" WOD similarly to the 6th circle player (without the SDI of course..). But it will take a little coding. Then also they will need to leave the PVP out of this calculation..which would, as it should be a complete nerf of pet WOD against players, i.e. make it completely ineffective in PVP, or the balance change will be very damaging..
