Given there was no prescribed limit nor specified delivery schedule at point of sale of the LEP... there is never going to be legitimacy to complaints about pace of delivery, it is that simple.How much longer do people need to wait to have "the legitimate right to complain about pace of delivery"?
As a Horizons era LEP owner myself, I realised what FD was or was not committing to - it was written in black and white as part of the LEP description. No timescale specified. No specific sequence of content nor packages of content, beyond what was being already announced for the Horizon expansion.
As for trolling (attempt or otherwise), far from it - simply stating actual fact. Some may think they have a right to complain, and to a degree that is true. However, FD have all along been rather vague about their feature delivery plans and often only release information almost immediately prior to release (or at least at point of the Beta phase). At no point have FD stated a plan for delivery beyond a performance period of 12-18 months and while people may object to the pace of delivery FD have never actually committed themselves to a particular schedule for Premium Expansions and probably (if they have any common sense) they never will.
We should all know what happened with the plan for Horizon and how many complaints came out of that plus how long it took to complete. We also know that they gave up on the staged delivery model for expansions after the community fallout over Horizons. Given all of this, the fact we only know of the pending E/O 2020 Premium Expansion should be of no real surprise. By the time they announce the forthcoming expansion it should be on the most part complete and people should know exactly what is being covered by the expansion BEFORE they buy it.
I can not blame them for keeping things close to their chest, announcing the plan in advance and then alterations along the way as things change has never worked out well for them from a general community relations perspective.
