i paste it from the steam forum, because it seems important to me. Or maybe i don't understand fully the mechanic.

When we equip an item with %resource generation, our basic attacks get %bonus to rage generation, but for example skill sovereign shout gets a penalty and after equip such item, it generates less rage, and it should be different i believe.

i attach some screens, after equipping an item with 25% resource generation.

basic attack, before equipping 75, after equipping 94

sovereign shout, basic shout generation 300, and after equipping an item instead of rage generation increase, it gets decrease to 252 (same story with wings of ishmir)
