Its Self-evident that EoD as a concept only came to exist early on after Ibs was set up as a more ambitious lw season. Based on the announcement trailer bits and story bits that where introduced and now seemingly dropped in light of EoD comming 2021 its clear that the original scope and goals of ibs has changed sagnificantly (likely shrinking in scope).
I dont make this to tell you oh you should have done this or that, i just want to stress that really, the champions release started on the weak side (even for ibs release standards which have been smaller but faster to produce traditionally). The scope has been a mess and thats because you havent set a clear plan for how Gw2 is going to stay relevant and evolve and grow for years to come.
I Hope you take the time leading up to and after EoD and decide what the model for gw2 releases should be and stick to it. MMOs have traditionally had smaller lw releases inbetween expansions which happen on a schedule, others just had expacs that happen on a schedule and others just had smaller releases that happen often.
Whatever you pick stay with it and optimise it so the administration of new content doesnt suffer outside of problems that you cant control (covid) and the game can finaly stabilise again and grow as it should.
I would personally go with the safe model of having expacs with lw inbetween, others might have other opinions, but please, dont just decide on the fly what to do, instead pick a course of action and stick with it.
