If you're rushing Chalice, do you need flat MR glyphs for it to have any real effect?
Whenever I rush a Chalice of Harmony as Lux or some other mid-lane mage, it feels like the 25 MR does absolutely nothing, or even at times that I'm taking MORE damage than before (even if that's just a perception thing). I normally don't go with flat MR glyphs on her, instead going AP/lvl.
Are those flat MR blues required to have that Chalice rush actually work in terms of reducing magic damage meaningfully? Or is Chalice rush a complete trap altogether?
