Shield Barrier theory crafting, need some input
So with the new Rage changes GC posted yesterday, it's pretty much impossible to NOT have maximum Shield Block uptime, which means Shield Barrier usage will become the difference between a good and a great prot warrior. (on top of not sucking at your rotation, keeping SB cooldowns rolling, managing cooldowns for big boss breaths and raging on the VoIP if your choice)
This also means that SBar theory crafting becomes more important, which is where I need some ideas from you guys.
Right now, I have always considered average damage reduction per hit, but with SBar there are more possibilities...
a) Increase base health pool by a portion of the shield, depending on Time To Live
-> extra HP = TTL / (time till 60 extra rage) * SBar shield value
b) Treat the shield as additional "damage reduction", based on how hard the boss hits
-> extra DR = shield absorb per second / effective boss DPS
c) Treat the shield as an extra chance to 'block' for a certain amount, based on boss swing & shield values
-> SBar 'block' = (boss swing timer / time 'till X rage) * (absorb value / full or blocked swing)
Obviously, simming would be the best option, but for simplicity, I'ld prefer one of the above for my spreadsheet, which is kinda annoying because (a) assumes some sort of EHP scenario and disregards rage generation, (b) assumes you average it out, which is counter-intuitive to it's stacking nature and (c) well ... is just a pain to get right.
Any thoughts on how I should view SBar when it comes to EHP, total damage reduction & burst reduction??
Also, would you consider bleeding off rage pre-emptively with chunks of 20 Rage or just pop one when you're at 90/110 rage to prevent capping?
PS: Shout-Charge-Shield Slam (ZR if you miss) = start off with SB instantly, you can even get it just from Charge+Berserker Rage (or Shout) if you got 2pT14 and the Bullrush glyph. How bursty is that for rage income? I really think they should've just upped the def stance rage generation to ~5 every 3 seconds
