@
Arker42 What do you mean 'an emergency situation'?
The only time you
ever cast Ignore Pain is if you 1) will cap rage if you don't, 2) have a proc that makes it bigger that will go away before you would otherwise cast it, or 3) if you will die if you don't.
There is no reason to cast Ignore Pain at any other time, without a free revenge, because you're just wasting rage on revenge.
Now, if you're generating a lot of rage, you're going to be casting a lot of Ignore Pains, because otherwise you'd cap rage. And you can plan in advance for that - if you know you're, say, on 80 rage now and you're going to generate 150 rage over the next 5 seconds then of course you're going to start spending ASAP. And if you're, say, on 30 rage, and you know that that's going to happen shortly, then you plan for that too.
Perhaps I could word it so that you understand better, but my guide is not incorrect, you merely do not understand what "having to cast Ignore Pain" means.
Why would you cast Ignore Pain in any situation other than the above descriptions? Except perhaps if you had like, a gigantic str/vers/mast proc or something, but realistically that's not going to be important
