Guild Wars 2 is a MMORPG, that also has a strong PvP component in the form of WvW (World vs. World). This is where servers are categorized into tiers and then three servers at similar tiers are pitted against each other, with members of those servers meeting on a special battleground where they fight for control of certain control points, gaining points for the server overall.
At the launch of Guild Wars 2, Henge of Denravi (HoD) was one of the largest, if not the largest, servers in the game. They were tier 1 and undefeated. But, as the stories go, people started transferring from other servers and joining HoD WvW so they could relay HoD’s battle plans back to their servers of choice. Also, there can only be so many people in WvW at one time, and the stories say people would transfer from other servers to HoD and join WvW then just stand around to fill up the queue, preventing the more skilled and organized guilds from joining the fray.
Those guilds eventually got tired of these tactics and left the server, joining other servers instead.
Originally Arena Net’s idea, the company behind Guild Wars 2, was to make world transfers, where you transfer your character from one server to another, free at first so players could be sure they were on a server they liked. Then, after a time, world transfers were supposed to start costing real money, but that hasn’t kicked in yet. That’s what allowed all of this server hopping to happen.
Because HoD was in first place for so long, it’s still ranked in tier 1 despite now having a much lower population than it used to. This means that it keeps getting pitted against much larger servers where it can’t make much of any gains, with point spreads of 100,000 for the large servers and HoD with something like 5,000.
It’s expected that HoD will move to a lower tier at some point. When world transfers are no longer free and when the tiers are reshuffled and rebalanced, it’ll be interesting to see how well HoD starts doing. Who knows, maybe it can climb its way back up the ladder again.
