Admittedly, I subscribed primarily just to get the "Easy Button" subscribe option for the newer v1.174 Diplomacy (with other fixes and such from Wulf). I appreciate the modder porting this over here, because I found a long list of Diplomacy-embedded mods but most fall into one of these 2 categories:
- Old version of Diplomacy, but you can easy-subscribe/install in Steam.
- New version of Diplomacy, but you must visit a 3rd party website and download/install.

So, you've really helped out the M&B:W community by porting this over, regardless whether a player wants to do the victory shout after a victorious battle.

Edit: I am also making a "Suggestions" thread here in the Discussions, to help compile a wishlist of potential mod tweaks to additionally add to the current Diplomacy mod as you have made it (and for Wulf's consideration as well).
