Guild Wars 2

In PVE you run into NPCs blocking roads with stuff that needs to be destroyed to clear the road.

WvW have siege that is medium-expensive, and requires a few people to deploy. One person uses the siege item, and can use 1 and 2 to rotate angle, and when locked, shows 3 circles on the line where other players will have to stand and build.

When inner gates at keeps/towers/SM are breached and a zerg is rushing through, even if you have a bunch of traditional siege set up, they will overwhelm and wreck the siege. Barricades could be a strategic option to slow down chokepoints.

Barricades could scale destruction HP based on amount of enemies present or siege deployment cost (player could say “lets spend 100 siege on this barricade and have it be very strong, or 30 siege on this barricade and have it not be strong”). Scaling is better because if gank team barricades supply camp exit, instead of flipping, yaks could destroy in a few min.

I already made a suggestion for a new blueprint “Barricade”. https://forum-en.gw2archive.eu/forum/game/suggestions/New-WvW-blueprint-Barricade/
