Well, I will say that any “excess” gems you have beyond the daily bundles are still obviously best used in VIP Chests so it’s still useful to have access to. And there should be excess. Buying the daily bundle is only 350 gems/week. Just the Blue Tasks give you like 100 more than that (starting next week). And you should be getting gems via other avenues (like Tributes and GW).
To the extent you’re only getting a couple hundred fewer gems per week, which I think is true for most people, it’s still a net gain. If 50 VIP Chests is the equivalent of roughly 300 gems/week over 2 months. (And I seem to recall someone doing the math and showing that 50 VIP Chests only gives you something like a 60% chance of getting a Mythic?) That says to me that a guaranteed mythic every 2 months is well worth a 300 gems/week reduction.
You can say, “I wish I’d never had to buy VIP 5+ since it’s not nearly as necessary now!” but the game might not be around to make it less necessary if it weren’t for that spending in the first place.
