Bulwark

[JackFross]

First, I'd like to say that Bulwark isn't true mitigation like "Rampart" or "Shadowskin".

Bulwark only increase Block Rate by 60%. There's that other 40% where it DON'T trigger.

Couple Bulwark + Sheltron, and you're safe.

It's less than 40%. Your shield has a base block chance of >0%. :0

Never couple Bulwark with Sheltron. That's silly. Sheltron is an instant block. Assuming you have say 15% block rate with your base, using Sheltron alone is +85% block rate. If you use it with Bulwark active, you're sitting at 75% natural rate, so Sheltron is only doing the extra +25%. Unless a physical tank buster comes in the duration of Bulwark, Sheltron is strictly pointless during those 15s.

Finally you can't block magic attacks, so if the tank buster is magical or the trash pull is magic only (like elementals) then bulwark or any cooldown to do with block/parry is redundant.

It's not redundant. Redundancy implies that you're stacking something with one effect on top of something else with the same effect when the additional thing is not necessary. A good example is the above - using Sheltron during Bulwark is redundant. Stacking parry on a Paladin is redundant.

Using Bulwark or Sheltron against a horde of elementals is useless, pointless, or ineffective, not redundant.
