Well, if past performance is the best indicator of future results, they will:
Devalue existing currencies
- Just as alliance points, and gold (to some extent) have been devalued, trophies and TV stones will become less important
Put all new desirable items only in Orsinium
- As with nearly all v15 mats only in IC
Remove incentives from being in current zones by providing greater rewards in new ones
- Such as making pvp kills more valuable (+tv stones) in IC than in Cyrodiil
And of course, there will be a grind for a new motif that requires 10 X to make 1 Y and 10 Y to make to 1 Z.
- This will then be sold for $50 on the crown store two weeks later
When Orsinium comes out, the city and sewers will still have a few people grinding CPs, and some people trying to gank them.
Everyone else will be in the new zone. Unless their approach changes.
