We understand the issues with the DB and the various other issues that the merge caused. Those are short term and will be fixed. Please do not add those to the list.
In regards to PVP rewards, pricing and writ giver locations - The current items, prices, locations are not changing but they will not be as easy to get in the next expansion. The current goal is to make sure the vast gap between tiers was bridged and that any new items added in the future will be the desirable items to work towards, rather then ones that most hardcore players had already purchased and then banked due to item quality at the time.
