What WvW is currently lacking: People don’t have the feeling that developers even work on this game mode. We’re getting events for PvE and PvP has their seasons. WvW hasn’t had any tournament/event since a long time.
My suggestion: Do an event each week, exactly 2 days before reset, so the whole Thursday and Friday. If several events have been designed, they are repeatable by random (but not the same event 2 times in 4 weeks for example, simple suppression of redundancy). Those 2-day lasting events should be fun of course, and give each matchup a fun ending (fun prevents salt a lot!). Those events should not destroy already placed siege, do not make a captured object neutral etc.
Events:
Siege related:
Explosive Golem Rush: All alpha golems cost 75% less supplies, have their health halved and explode on death! Alpha Golems now look like Veteran Dredge Mining Suits or Giant Risen (random!). Soulbound Alpha Golem Blueprints are available at the siege vendor for 20 WvW Badges (not useable after the event).
King of the Hill: Hills on Alpine BL and Air Keep on DBL give 10x the points when captured, but also 5x the points while being held! The siege-cap is reduced, go use your arms and feet!
Nokk’s Gravity Mess: Trebuchet and Catapult have their projectile travel distance capped at 50%. Shield Generators now push the players 100% further
Heavy Supplies: Each supply decreases your walking speed by 1%. For 2 days there are useable Charr-Battle-Bikes at the siege vendor for 10 WvW Badges. Each Bike 15 supplies to transform into (No siege, but transformation).
Environment related:
Payback Time: Animals (with white names) now have a stunbar, 10k health, are aggressive and do insane damage! (no Loot)
They got the plague!: NPCs are sick and have the daze-animation. They do halved damage and spread poison onto each player who is in a 600 radius to the sick NPC. Tower/Keep Lords have the barfing animation which poisons players standing in its … area. Stonemist Castle is now a fortress of sickness: Players or NPCs who die in SM create a poisoness green blobby field on the ground which poisons and weaken + cripple every player stepping in it. The poison of all those effects should be extremely low, but long enough to inhibit your heals.
Call the Undertaker!: Instead of going downed, you will be transformed into a skeleton with 10 bone counters and can fight with simple hits and kicks. Additional skill “Throw yer bones”: throw a bone on an enemy within range 600 and daze/knockdown/stun this enemy (randomly chosen). This skill does not make damage, and decrease your bone-counter by 1. You’re not able to use/place siege or pay supplies for building it. This transformation ends when you’re dead again or have lost all bone counters (there’s a 30% chance to lose a bone counter when you’re CC’ed such as stun etc.).
Pirates!: All NPCs are replaced with pirate NPCs, and make grumpy/drunken pirate noises when standing close to them. Keep/Stonemist Castle Lords (big grumpy Charr pirates) carrying the new rifle legendary and can now oneshot a player when screaming “ARRRR!” cooldown on this skill 3 seconds, not reflectable/blockable. All NPC-camps such as Hylek/Ogre/Dredge etc. are now Quaggan-pirates! Catapult projectiles now have a big portwine-projectile. Trebuchets are firing Quaggans with metal helmets to hit walls á la Evil Knievel (just projectiles, no actual NPCs). While walking around in WvW you will be able to find wood planks, a weapon item which can be used 3 times or be brought to the new supply caravans for extra swiftness: A Dolyak in a small boat with wheels!
Friday Might Fever: Night Fever? No Way! This is all day long party time in each Garrison and Stonemist castle. The Lordroom as a discoball hanging from the roof, making the room shiney! The Garrison/Stonemist Castle NPCs are busting out some awesome dancemoves! Even in combat mode they do a dance-off in increased speed, rocks and bulders are falling from the roof of the lordroom damaging enemies (just like the AC-rumble-Boss). Each boulder gives allies a might buff. Gives “Party hard” a new definition! Catapults and Trebuchets now shoot discoballs as projectiles. Other Tower and Keep lords are grumpy, saying stuff like “of course I wasn’t invited!”, “kitten Partyanimals!”, “Ohhhh my head…”.
More events could be added over time! Make WvW great again!
