If anet want to truly do something different from the norm regarding this expac how about a spear for warrior as the main added weapon but also changes to gs,sw and bow skills to fit the theme better. As a mechanic f1 and f2 are offensive and defensive stance giving the warrior access to different effects to each weapon skill and burst skill on spear,gs,bow and swords. So u could pop f1 to use offensive skills on gs as a example than hit f2 to have a sec weapon kit on gs that's more defensive, the cd on the f1 and 2 skills could be on 9 sec weapon swap and 5 with fast hands for some synergy.
I think that would not only make warrior feel significantly different it would be a change of formula from last two expac all while sticking to theme.
I know people are thinking god another ask for a samurai spec lol.
