Sorry, kopcap, I lost tracking on this for some weird reason.
Couple of things.
1) When I said “wasted”, I meant you can’t overlap Shield Block or the old Shield Barrier; there’s no point. Also, after the magical nuke, the remaining duration of 25% less magical DR is doing nothing.
2) “You always know when you are going to use it and what you are going to use it for” is exactly why the developers don’t like it. As players, sure, it looks attractive – but the developers are looking for something with choice and a bit more depth than the previous system.
3) I’m aware that chaining absorbs leaves you without Shield Block, but it doesn’t have to. You can build a decent absorb up BEFORE the spike we’re talking about, then still have Shield Block up for it; so say you pool to 100 rage, use the new Barrier prior to the pounding, then use Shield Block. That’s planning ahead and making a decision, and it’s more compelling than the old Shield Barrier because you can do that with physical spikes that otherwise can’t be blocked (the aforementioned Focused Assault or Impale).
Yes, those mechanics are design issues and not class issues but if warriors have a way of managing them, they can stay in the game more safely.
From the design standpoint, I see no reason why the absorb can’t be 90k; death knights can already manage that, and remember, we’ve got to look beyond current itemization.
The other important point to note about this is that it’s very likely the new Shield Barrier will be buffed by mastery once it’s tuned properly. I say this because the paladin mastery now affects both their block value AND Word of Glory (via Bastion of Defence), which means warriors are very likely to see the same treatment. Otherwise, it leaves mastery as a stat in the toilet and I can’t imagine that’s the way the developers want it to be.
