OK then in that case I’ll give you a hands on example about what happens when you do that.
At the end of Legion (before we gave up our artifacts and before the level squish), my heroic geared prot paladin was fully capable of running an m5 with no healer.
So when those two changes came into effect, said paladin with exactly the same gear was barely able to do a random heroic violet hold. I saw my health bar rapidly drop to below 50% on multiple occasions and it wasn’t because I was ignoring mechanics. It was so bad I could barely solo a rare mob on Argus.
So I decided to equip Prydaz (the legendary neck with the shield) and almost never saw the shield depleted. The lowest I saw my health at was 97%.
This is a great example with a big system with other systems interacting with the big anchoring system. Now please look at the end result and tell me that my paladin being barely able to function properly on world content with heroic gear from the final raid at the end of an expansion makes sense.
The best part is that I was forced to give up the thing that made it sort of work at the start of BFA because Magni showed up and gave me a necklace and said “here you go, you’re stuck with this now”.
From a gameplay perspective, please explain to me how this makes any sense.
