Due to the weighting effect of imbuing properties, you most likely will never see an imbued item with 5 properties at max intensity. With high end runics (val/heartwood) there is that possiblity but the odds of getting all 5 mods that you want is the super rare part, so it is a trade-off, do you imbue a weapon that will have fewer mods but the ones you want or use a runic and take your chances.
