Firstly:
@Marindor - many thanks for the info, and
@Kersepitje - hey forget it, but thanks... you should have seen MY first-draft reply to you...!!
Secondly:
@Enevhar Aldarion : I personally would be DISMAYED if Artifacts in particular were removed to the category of 'not Disenchantable', because these are currently my PRIMARY source of any urgently needed large amounts of Spell Fragments, and will remain so for the foreseeable future as well, albeit reluctantly because I have a strong feeling that some other purpose for the many unwanted [at least in respect of their related Evolving Buildings] Artifacts which many of us are now amassing is very probably on the cards, sooner or later - whether that be something we players have suggested (e.g. Artifact Fragments or exchanges) or something else which Inno may prefer. And I am not alone in seeing Artifacts as a useful source of Fragments, either - in fact, most players with whom I've discussed this topic also regard the [typically] 1-5 Artifacts they may win in any given 6-week Spire 'Artifacts session' in much the same light... so I'm not being purely self-interested here.
However, what I personally
can't see continuing for the indefinite future, if only because it doesn't exactly create a broad sense of achievement and thus goodwill amongst the early-game players Inno is so evidently courting these days (and others, too, for that matter), is the situation where many players are increasingly becoming aware of (and discussing, not least on Inno's preferred communications platform, Facebook) the reality that only a very few players are fortunate enough, under the present RNG system, to win from the Spire
enough Artifacts to make building the related Evolver(s) a feasible proposition, short of serious expenditure in Crating to boost the total number won, at least.
Now, unless the system is altered so that many more people win a
realistic number of Artifacts in the Spire (I'd say 7+ of any given type would be a fair guess as to what most people consider 'realistic'?), this naturally then calls into question the validity of [what is, for many players] the high Resource/Troops cost and time investment (and luck level!) involved in winning said Artifacts from the Spire - which then tends to undermine the Spire's general popularity - which Inno are likely to see as detrimental, to say the least, since the Spire (and Crafting, its closely related cousin) have been quite intentionally moved into a central position in the game and then further promoted ever since. Inno didn't do that for laughs, I'd say, and although I've said below that second-guessing Inno isn't very wise, in my experience, I think I can safely say that introducing [and frequently amending] the Spire/Crafting has cost them enough to indicate that these are two in-game features which they'd very much like players to admire and see as valuable and worthwhile - not to find frequently disappointing and/or eventually regard as a little more than a late-game Resource sink.
Furthermore, although it may seem bizarre to many - and while I myself am not,
as yet, so desperate for Spell Fragments that I regard Timeboosters as a primary, or even last-choice, Disenchantment candidate - I would also not wish to see Timeboosters, either, removed from the category of items which can be Disenchanted. Many of us, self included, have a large Inventory of these as well, and Inno seems so very keen on putting desirable items into the Crafting menu that I would not take any bets that we won't see a day when something - whether currently existing or yet to be introduced - appears in Crafting which is so desirable that people will happily exchange at least some of their Timeboosters for such a theoretical item (or items...).
After all, it's well known that some players are happy to burn many Timeboosters in return for an intangible reward with limited appeal, namely a top FA Ranking (I doubt whether many Fellowships fight for the top FA spots solely, or even primarily, in order to earn what is for many of them a duplicate of a trophy building...), so I'd say it's far from unlikely that a situation may arise in future where players become willing to exchange those same Timeboosters (via Disenchantment) for more 'tangible', permanent, and - especially - desirable/valuable building(s) or other in-game reward(s).
What if, just for example, the currently extremely popular Sip of Clarity (which many players, self included, can't afford to even TRY to win from the Spire each week, and thus see as notable rarities), or the also very favourably received Tomes of X or Y now appearing as Sorceries, were to become Craftable... whether with Artifacts as their ultimate reward, or something even more valuable which Inno has not yet dreamed up? That wouldn't surprise me at all, and if such happens, then I - and others of my acquaintance - would prefer, at that point, to have as many items available for optional Disenchantment as possible. More choice = good, in my view.
Furthermore, and in the same vein, who would have predicted,
before original Phoenix and Bear bases and Artifacts became permanent Crafting items (and near-essential in-game buildings to own, for any even vaguely Combat-orientated player - and far more so since the 2020 and more recent Tourney changes) that there would be ANY reason good enough to induce players to willingly sacrifice Blueprints, of all things? But here we are... I, and many, many others I know, have done exactly that - plus a goodly number of hard-won Diamonds, too, since I pretty soon ran out of the few Blueprints I had (not to mention the necessary 10K Spell Fragments per Artifact, too... as I say, always in short supply for me, at least!).
In fact, NOT second-guessing Inno's future plans forms the basis of my in-game strategy... to the extent that I hoard literally everything which can be hoarded, as a matter of policy, even when this means that my gameplay speed suffers significantly as a result. I don't like [nasty] surprises...
