Sorry, I have to give you a yellow card for this due to unsportsmanlike conduct.
1. First, multiply the above by 5 or 10. Because that's how many times many of us repeated that same destroy-the-old-LI-and-build-a-new one routine. THAT was the LI grind that Turbine responded to, and eliminated, with ILIs.
2. Second, let's not forget other aspects of the old LI grind that you don't list above. Relic Removal Scroll. Crystal of Remembrance. The cost to buy a new Second Age or First Age symbol (or both). The cost for a new title scroll. The relic grind to get the new top-end relics. The LI-to-30 farming to get the higher level legacies to put on your replacement LI. And then multiply all that by 5 or 10, for each LI you constructed under the old system.
This last update, I had to do none of that. No relics to be removed. No SA or FA symbols. No titles to replace. No legacies to replace.
Instead, I got to keep the exact same ILI I had prior to the update, but I got to make it
better.
Yes, that improvement requires a number of scrolls and crystals. But that's because 8 or 9 tiers were added to each legacy. That's like building 3 old LIs, which would require just about the same number of crystals and scrolls as we're needing now (not even counting the scrolls of delving, etc.).
Has it been so long that people really have forgotten the pain of the old LI system? Count your blessings.
