If you are that concerned about "wasting" a proc, look into fireweaving.
Not to start the whole fireweaving debate from scratch, but wouldn't that just increase your time spent effectively not casting, similar to interrupting the next Fire I to use FS? The reasons given for not interrupting casts seem to support not attempting to fireweave since using an OGCD consumes a fraction of a second each time, or am I missing something here as well?
