The FM prize store with the exception to the top of tier 5 is literally full of obsolete tech and has been for simply ages.
Tell me, when was the Citadel last a viable hull as with Monoliths etc.
Tier 1 prize pool is virtually obsolete as events of any kind requiring said hulls are few and far between. Even "owning" them is pretty much pointless as there is literally no no way to rank them as the necessary is not freely available.
Spending a few coin here and there may offer some entertainment value but who in their right mind would want to spend literally thousands to play some form of catch up to be viable in the game? For some, including me obsolete tech = obsolete game.
