It is normal leading up to an expansion that we start looking excitedly towards what we will gain in the game, all the new stuff that will become available to us, but after seeing how a certain really big MMO has handled expansions in the past, most notably its most recent one I just have to ask - what will be removed from the game with Heavensward?

Will the Beast Tribe quests remain in place, so we can farm those mounts and minions?
Will the story in Coil be considered over and done with, with the raids removed to keep the current T13 farmers feeling special for being able to clear it when no one else could?
Will our achievements, particularly the ones building towards rewards like titles and minions, be reset or removed?
Will Triple Triad be expanded, or left as it is today? It's sufficiently new that I don't think it will be removed yet.
Will the (Augmented) Ironworks gear remain available? Will we be able to farm Poetics as an old currency to obtain it?
What of the current Relic quests - and relics, for that matter? Will they remain for people to go back and farm?
The old job-specific gear looks, ie. the i90 gear; will that still be farmable?

Does anyone know with certainty, not just a gut feeling that "They would never remove that!" whether these things will stay or be removed? Anything else I might have missed?
