Re: Cassandra & Iron Bull not using health potions
There are a couple of things I've seen affect potion use, but first let me make sure I understand what you've tested:
- You've switched up the % they're supposed to use them at, especially to obvious ones like "50%" so it's clear on the bar
- You've had all 12 potions and made sure the "don't use if we have less than X potions left" is far below that
If both of these are the case, then it might be they are spamming abilities too often. How are their Tactics set? If you have too many Preferred abilities, they can prioritize using them over stopping for a potion; it doesn't seem that checking for the health % and drinking a pot is an interrupt or top priority.
Another thing is, are they getting knocked around a lot? The "drinking" action takes a second to activate and complete. If they start to drink one and get interrupted, the AI seems to respond more to that than to the health %, such as Payback Strike, and if they are knocked down they can't do anything at all.
Try turning off ALL "preferred" actions, just as a test. I have 1-2 on most toons, no more; one might have 3, but not the tank. I have also disabled some of the long-cast or high-stamina abilities and do that manually.
Lastly, what is your stamina reserve set to? On most toons, I have it currently at 0, but those toons don't have more than 2 "preferred" abilities. I think if you have a lot of preferred and a low stamina reserve, they may just be spamming their little hearts out. Combine this with melee getting knocked down or smacked around and lot, and that makes it harder.
