Heroes and Signets?

I don't get why heroes rarely ever use signets...

I disabled all my monks spells but 2 sigets (signet of devotion and signet of rejuv) and the monk just let my party members die, rather than using the signets...

Do they only use them when they are low on energy? Or whats the deal...

Also, their AI is messed up in ALOT of ways (Not keeping on maintained enchants like life bond, etc) and that they use Word of Healing when someone is 495/500 health... A few things that could definately be tweaked in an update!

Anyone else notice anything weird that heroes do that they shouldn't, or don't do that they should?

mine tend to burn alot of energy healing minions too

One of my monks is set as a word of healing monk with restore condition, and he mostly just uses restore condition, when no one has a condition.

I gave res signets to all my heroes, as soon as someone dies, they all use it at the same time, sometimes cancelling out at the same time for no reason, until they die (they will start the signet, then cancel, until they're dead or the target is resed).

They use smite hex/inspired/revealed hex very well (on bird/passive mode).
I would like to see them use signet of devotion more aswell, they rarely use it.

The only hero I don't have a problem with, is the ranger, uses all her skills very good (unlike most rangers i know lol). And the necros are pretty good.
