Can warriors contribute to WvW?
absolutely. we have good ranged abilities, we can get into melee if we need to, and our heavy armor generally allows us to be able to do things like combat res or tank aoe while manning siege.
warriors advantage in wvw is our flexibility to do pretty much whatever needs to be done
my advice: learn about the intricacies of the other classes. if you know what theyre going to do, you have the tools to be able to counter it

They can however many of best tactics don’t leave warrior as an ideal choice. They are great in smaller objective groups, running supplies, and scouting to name a few things. If you have GS/Sword & Horn out you are the most mobile class in the game but always carry a ranged weapon as well. On keep defense having 10 points in strength and defense is also incredibly valuable, use sword and board along with the death from above and missile reflection and you can jump off walls onto invaders and reflect projectiles back at them as you run back in. Rinse and repeat.
Just use free no skill kill shot or knockback chain for 100 blades.
Warriors have great tools to break into enemy lines to break the balance of a mostly ranged zerg fight, a lot zerg fights start breaking the balance when few warriors charged in and start pushing; also warrior can provide great group buff with shouts.
If you want to be a frontline melee character in WvW I recommend playing a Guardian. They don’t hit as hard but they do have more survivability and better condition removal than a Warrior. Which makes them more suited for the task.
