We hardly ever remove gameplay content; discussion on this subject is for another topic.
Then let me start a new topic that will be 'On Topic'.
Defood was removed.
Complete Sanctuary was changed.
Lightning Shock was changed.
And various other "gameplay content" was changed/removed.
So now, as a GM, you should take responsibility and tell us WHY stun won't be changed. How does it better gameplay??? How doesn't it better gameplay??? It ruins gameplay in my opinion.
