well for me it depends on the number of diamond i hv on me
if 1= trap
2= prot
4= sharp smtyms depends on the situation where m in a tight spot so i get sharp first
rest all in upgrading armor dats all nthing else
thats for my solos and doubles
when it comes to QUADS : i first buy trap then prot n sharp later then upgrade the prot if my opponent team is a party or gud team i would upgrade my forge too along w it
well in bedwars just diamonds are >>>emeralds i hv seen new comers and mediocre treating diamond as sm underrated stuff :/
