Stats not letting you survive past torment 1

I have been playing a lot of the seasons and have been able to beat at least the 4th seasonal missions because i dont have to be on torments higher than i can survive. My stats are lower than my follower in lvl 61 yellow and Blue gear when i am using level 70 green sets. I have less armor rating and Vitaliy and cannot survive a hit from a small minion. I have checked my build and made sure that it is not user error this is a flat out issue and makes the seasonal missions unbeatable if i go past torment 5. Even looking at my friend’s stats on his game i can tell something is horribly wrong and when we play together its a nightmare. I cant take a hit from a small zombie and he can take hits from elites even though i am further along in my build. This needs to be addressed.
