None of the things I listed are usable for Fury PVE in Legion, which is what I play and I liked all of them, they were fun and made my favorite class that much better.
And how are any of the things I listed not good for the game?
Do we really want to break down why every single ability got removed? Most of them seem pretty straightforward.
Spell reflect is really neat, but how much does it belong on DPS warriors? Thematically it makes no sense, you just kind of raise up this shield from nowhere. Being targeted by a spell was a rarity, and having a reason to reflect instead of using an answer like pummel was something even rarer. How often would the reflect even provide a damage bonus over the buff you could get off pummeling? You needed Mass Reflect to really make much use of it, which rarely provided returns. Its uses wind up primarily being PvP (where you can still pick it up), and cheesing stuff like Challenge Modes. Instead the ability can be refocused to Protection where it belongs and boosted up to combat magic damage in a more general sense.
Intervene is really so similar. Extremely narrow use cases that thematically does not fit a DPS warrior at all. Part of the mess that WoW got itself into, particularly with Mists, was the amount of stuff shared not just between classes, but
inside a class across specs. If you are a damage dealer, particularly one that takes more damage than anyone else, why do you have an ability to intercept damage on allies? Instead Warriors can find mobility elsewhere through stuff like Heroic Leap.
You miss a heal that doesn't need Bloodthirst? How many do you need? Enraged Regen is still there. Survivability needs limits. You miss Heroic Strike? Why does a GCD capped class need something extra to press after we saw what a nightmare it was with Gladiator? And maybe it's just personal preference, but the banner stuff just does not fit the aim of what a Warrior should be in WoW at all. They should not be buff bots. The arms race for middling raid utility had to end.
