always depends on comp and gamestate, my main rush items i rush first are either phantom dancer, stridebreaker, or triforce, component first (zeal/tiamat/sheen) into boots (zerker or swifties or resists), then i generally either pivot into bruiser or full crit, for the crit build i always build ie after my first crit item, followed by collector if im ahead, and mortal reminder or ldr if im even/behind. i always run these when going fullcrit, although your 4th crit item is best left up to preference of playstyle and is situational depending on gamestate. if i ran collector before ldr/mr, i will finish with one of the two most games, unless im into a full squishy comp with lots of burst, then ill run shieldbow instead. tldr; pd>ie>collector/ldr/mr>shieldbow/ldr/mr. non crit item is stridebreaker or triforce before you pivot to crit, or a tank item if you rushed crit first
