Nashors Vs Shojin for AP carries
I am still pretty new to the game, i only started playing tft at the start of set 13, and i already reached diamond, i feel i have a good understanding of items. But i don't understand the obsession with shojin for higher mana ap carries, is the appeal of shojin because of the versatility? since you can put it on either an ad or ap carry? but if you're locked into ap items such as spark and shiv why would you ever build shojin over nashor?
EDIT: So i did some math, i made two quick cases and it appears nashor is way superior when it comes to longer rounds, but Shojin is stronger for shorter ones especially since it gives 5 more AP, but nashor is more suitable when it comes to champions with higher mana cost.
EDIT: After including the nashor buff duration, for champions at 80 mana the two items become pretty close with a slight advantage to shojin. I will do more numbers later when.
