I know how it works and how it was intended to work.
However, if you would use it against certain creatures, it would just not work appropriatly. As there are creatures among those that are as to say hasted permanently. So thus they wonder around, flee from you, but you will NOT have enough time with the 20 seconds to run away. I know this because it has happened allready, not to mention that often even the creatures that are turned or if the warding gesture was used on them, will still attack you.

Also you can only use spells, potions etc. to escape if the gesture works on all the enemies. As in there is not a single creature among them that does not fail the save. Sadly this is often not the case.
I also know that this is quite the RP tool that can be used greatly.
But! The gesture has quite the prerequisites, as it requires the character who wishes to employ it to have a wisdom score and a charisma score of at least 11.
For a number of classes to raise these attributes to the required level will not make much sense.
What you stated actually is why that taking this feat over others along with the prerequisites is the main reason why many classes will not take this feat or consider it usefull.
It is why i offered these suggestions to improve it slightly.
However it is possible that i again confused the turn and round in NWN system.
I meant that for every 3 level the duration of the gesture should increase by 6 seconds. Perhaps every 4 levels or 6 or 7?
It would not offer such a great bonus to the feat, it would still make it the way as it was intended, however it would offer some growth along with the character development.
As a character grows (in levels), i allways assume and like to think that the characters devotion and ambitions and faith grow, they become more dedicated and thus this feat could represent this in such a minor way.
Actually i would say the warding gesture feat is more akin to favoured enemy in comparision.
So all in all i think that giving an extra use per ever 5, 6, 7 or 10 levels, would still not be that great of a bonus. As the DC with which you employ the WARD grows fairly low with most classes. (My cleric reached his limit where it will only grow with his level, and it is barely over 20!)
The same applies with extending the duration of the ward by 6 seconds for every 3-4 levels. All in all with a level 20 character your ward would still make the enemies be chased away for less than a minute, perhaps even less than 55 seconds!
With every 6 levels +1 and every 4 levels +6 seconds on say level 18 you would have 6 wards, which each last for 44 seconds. With this you would have some minor(! since their saves will likely be high!) chance with your character to ward against things with 23-25 DC (depending on your cha bonus). Which i think is NOT that high, not that powerfull. You would likely need to employ several wards to have a chance to make an opening to get away for you and your party. (With my cleric I allmost never solo, and actually warding gesture usually is the way with which i could open up a path of escape, if the undead are that high of level, since even with sun domain there are creatures you cannot turn)
