Banner Warrior Suggestion
I like your idea but it would waste a secondary slot so here is an improvement.
When you harvest a banner on a Warrior you get a another profession skill that allows you to wear the Banner.
Once you’re wearing it, that profession skill allows you to switch to weapons or back to banner.
This way we keep the usual weapons but also carry the banner on our backs.
I’d prefer having the banner on my back and access to both weapon sets myself. We can keep dreaming. Giving warriors all the benefits of banners with both weapon sets would be way too good and everyone would take 30 tactics to get it. Perhaps if you made a trait in the defense 3rd trait slot that lets you wear a banner on your back and use both weapon sets it may fly. There has to be give and take and from what I’ve seen develoeprs almost always take more then they give.
