With minions (not focused only on golem like during s4), till now, i did t6 infernal horde and tested till pit 90 with 8/12 gear (not even close to have very good stats overall) and not yet lvl 21 gylphs,
Need to try t7 with minions and pit 100+ (for the pit i read that is the pit version before the nerfs during season 4, so i guess pit 100+ should be a good achivement)
Btw OP maybe it’s your build if you struggle in t5, from t6 i can agree that is a big jump but it’s still doable with a not “very good” gear, the only annoying and long part is killing the 3 bosses at the end; with a very good gear i think you can do easy t6 with minions
