It's probably one of the biggest errors in the game (not just crafting)
I understand what you are saying and I've honestly come to the conclusion that the best way to play this game efficiently is tragically to unsub for 6 months and then come back (or even more efficiently rotate every 3 months). This might not make sense initially but it's an error at the very core of the game.
Because they make timesinks in 6 month rotations, opting out for a rotation means when u come back that sink will be less formidable, but you end up able to complete it more efficiently later. So what implemented to sink the content is either completely able to be bypassed (like doh/dol) or becomes unlocked in dow.
About the only aspect of the game this doesnt particularly apply to is Relic DoW upgrades, but those are never as good as what u 'can' get without bothering with that system. There is a possibility this will be true also with the DoH/DoL upgrades and they have more potential utility than the DoW relics since there isn't any instantly better and rival options at their release but there's no way to be sure until their 6 month rotation occurs.
Of course another way to do it that doesnt involve unsubing is to do DoW for 3 months then do DoH/DoL for 3 months, but trying to stay current at both at the same time throughout is completely pointless the way they have decided to go about implementing content. But that way depends on whether you see the value in the sub if you abandon one part for another every 3 months.
Rotating what you do when u play every 3 months can be detrimental to the groups you play with if they don't agree with the utility of it, but the 6 month life-cycles of the game makes it to where if u do manage this appropriately you can get more done with limited time over-all.
