A company needs money for development, it's natural. The MMO market is not as dynamic as it used to be.
GW2 offers lots of stuff for free, that's great.
My idea is, let ArenaNet send a survey to every user what he thinks about the optional PREMIUM game model.
Every free user will have access to the entire game, both the cradle and the extras.
Let Premium cost no more than $ 9.99 (i.e. less than in WoW).
What must PREMIUM offer?
There will be additional opportunities to buy home furnishings in the store.
Let there be a new profession for players, available to everyone, the production of home items.
Premium will be available for purchase ONLY and only by real currency, not by exchanging gold for crystals.
GW2 has a large user base who will be happy to pay for their game to develop.
