I like how you manage to remember that crit items are multiplicative scaling but ignore how getting three of them(IE and 2 Zeals), as you're intended to do as a crit ADC, also gives you 120% crit, thus over capping you, and thus meaning you just wasted a shitton of gold. How many fighters are wasting 800 gold on their 31 item spike? None because all of the stats on Trinity have been morphed into stats that fighters like regardless.
Also, wow, 3733 gold for an item that literally gives you everything you need to actually be a champion compared to 3400+2800+2800=9000 gold in order to barely function. Its as if, by itself, Trinity force, without looking at its passives, is 94% gold efficient. How gold efficient is IE by itself? 72%.
