Guild Wars 2

Just an idea:
World xfer discount every 3 months.
I guess many of WvWers and guilds get bored on their current Tier/Server, they were looking for some new environment/challenge. However, the exfer fee is not cheap nowadays, especially when you have hundreds of ppl on the xfer list(for some big guilds).
Make the price more affordable once a period of time (I would say 3 months is a good start)— maybe 30-50% of now.
Then —- WvWer/guilds are happy with their new home/challenge, It also auto-balance the difference between tiers, and Anet get more money. (Walmart earn much more than Hermes) Both happy.

Or they could just fix the population measurement metric so lower tier servers would be cheaper to transfer too period rather than lying to new players and new customers and making them think every server is Very High population.
