To elaborate on my line of thinking with the numbers given (and again, important to read my edit - we won't be getting any official numbers anytime soon. But getting a general gauge on what's realistic is really important, hence the suggestions and request for Ngreth feedback): When coming up with some alternative ideas, I considered what kind of foci other classes have. One that stood out in my mind was the tank Fortitude/Deflection foci. These are discs with recasts of similar length to IoG, with an equally powerful (if not more so) benefit. I realize this is comparing apples to oranges, as one does something completely different than the other, but the "how much power do i get from X" line of thinking is still there. Hence my suggestion for the effectiveness of IoG (or hazy thoughts, as in suggestion 2) This is what I would aim at proposing, yes. Note that, if implemented as suggested, this would only affect critical damage and not base damage. As such, even a 10% focus would be a small (ish) increase. Hence why I think it's reasonable to extend it to all four spells in the line (Mindblade, Mindscythe, Mindcleave, Mindsunder). The idea behind the inclusion of the entire line is that it "future proofs" the chest item, while allowing it to remain 100% relevant. We're talking about a focus available on a level 105 (or higher) item. They aren't going to go back and revert items from previous expansions. As such, our priority should be things that are effective at that level. Stay on topic!
