Improved Expertise

I press imp. expertise feat, go into battle, it activates.
After receiving 1 - 3 hits it deactivates...
dafuq?

I believe it is auotmatically turned off whenever you cast spells, to prevent those 70 AC battlemages.

I believe it's bugged...Because:

a) I can't cast spells in dragonshape. (unless pulse is counted as a spell)
b) It happened while bashing the Axfell gate, it happened while fighting the boss who gives you codex pages, it happened while...

I could go on, but it really cancels even during the fight

I've gained some more knowledge from my assault-testing.

It seems anytime I get hit while in improved expertise during the combat(in dragon shape), the expertise automatically cancels.
Happens both with ranged or melee attacks...Quite annoying...If you could figure out what's causing it + fixing it, I would be grateful...
This bug completely messes up my build...

I have also noticed that on my rdd improved expertise will just cancel itself kind of annoying

EDIT: Just went on an assault and yeah at the moment the feat is basically useless

It's like yeeeah! Shoot your arrows, morons!
*guard rolls a 20* $#^%$#^%!!!!!!!!!

Hmmm I know we just have the normal bioware impr expertise cancel method in I believe.

Speak plainly!

Sorry for the confusion. Moth implemented the improved expertise cancel after feedback from the player base regarding casters gaining bonus ac for no drawback to themselves because they do not melee. Moth put it in and just used the bioware embedded option. If someone finds a fix and can implement PM me. I am extremely busy at this point and cant spend time at the moment. (new parent).
Thanks!
