I know this is unlikely to get serious attention, but I'm just so fed up with this, I feel the need to rant :/

Vizier is an amazing champ - honestly, probably one of the few that absolutely define a CB team.

Unfortunately, the AI is absolutely braindead. Nobody uses Vizier on CB for the A2 and A3. Yes - at a certain point, the A3 becomes useful for survival. But until that point, the A1 is the only thing that is important.

Putting Vizier on auto means the A3 gets used first, which is useless at the start, and most likely means the important debuffs fall off at the start. He then uses his A2, which means a bunch of useless debuffs get put onto the boss. Finally, he uses his A1, which means those useless debuffs stick on the boss.

On manual, I can very easily get seven poison stacks, poison sensitivity, leech, and atk down with Vizier, FB, Corpse Collector, and Sepulcher Sentinel. On auto, it's next to impossible. Even if I manually play the first few rounds to get the right debuffs to stick, once I set it on auto, there's a very good chance they'll fall off, since half the turns he's not using his A1.

IMO - the AI should be: if Vizier HP is below 50%, use A3, otherwise use A1. Never use A2.
