While I agree with most of what you said, you can't seriously think that you're really going to be using that i245 weapon much at all in the next raid tier. The patterns show that the new Warring Triad fight in 3.4 will drop an i250 weapon, and most groups will be farming those before doing much of final Alex Savage, if any of it at all. So at most it'll be an advantage for the first week, then you'll have the primal weapon and be using that to progress through the tier until you get the next Tome weapon. Is it really worth the effort for at most one week of actual competitive advantage?
