Guild Wars 2

Imagine, any server who has control of the Stonemist Castle can invade one of the rival servers’ Lion’s Arch. The invasion will only be 10 minutes until the invaders dissipate into a mist and return to Stonemist. The invaders can kill anyone and anything: NPCs (no kids ofc), Merchants, Black Lion Traders, Quaggans and other Players. Also, the invaders cannot port out or get out of Lion’s Arch. For 10 minutes, the invading server can rack up some loot and badges. The invasion can only happen every 3 or 4 hours, and it will not reset if a new server gets hold off the castle.

Why do this? Well, it could help mobilize some PvE players into joining the war in the mists. And it would also be fun and interesting.

The carebears would go mental if this were to happen.

1. Anet and many players have stated that apart from the occassional holiday or big event, cities should be a safe zone.
2. It would lag the kitten out of top tiered LA. Most servers already have overflow issues at prime time in LA alone anyway, imagine if 100 players from an invading server came in.
3. Because of number 2, players who really dont wanna pvp will complain more, as it directly effects them and lag makes it harder to escape zergs.

No. Both for the reasons Parlour mentioned and the fact that the different modes (PvE/WvW/PvP) should be kept separate as far as actual participation. Being able to to what you want is a big point of the game, forcing WvW on people that want no part of it is an idiotic idea.
