So your characters and all of their progress, levels, achievements, inventory, etc. will all be coming along for sure.
As mentioned in the blog post, the level cap will be increasing from 20 to 30, though. So you will no longer be ‘max level.’ (As is typical in most MMOs).
The dragon pet system will actually be receiving a lot of enhancements but your existing dragons will come over just fine in terms of the breeding, sizes, colors, etc.
One thing I do want to note on the gear, due to the new Avatar system we are rolling out, the current existing gear will not work. So, when the expansion first launches, you’ll have different gear (depending on what you had before). For those of you who have put in time to earn the higher-tier gear items (Shard Dungeons and Raid gear), that will be coming back as a transmog option for the new expansion, but it will take us a little bit of time to make that available. So just a heads up on that. You’ll want to be earning new gear anyway as you make your way from 20-30, but we want to reward those who put in the time and effort to earn that previous gear, so we want to give you the option of using it as a transmog look if you want.
