How big is the difference between lvl 83 and lvl 84 Mercenary

Pretty straight forward, how big is the difference between a mercenary from t16 and one from t17?
Does the one from t17 have better damage scaling, higher life, higher attributes?
Should i get one as soon as possible or should i not worry that much?
Im trying to make an aurabot and i wonder if it will be very important to get one from t17 to carry me one maps or am i fine with 83 as well.
Has anyone compared them yet?

There is no lvl 84 Merc. They are capped at lvl 83, as far as I'm aware. Iirc, even those in T17s are lvl 83.

Thanks for letting me know, i thought there are 84 ones on t17s

mercs in t17 are level 84 yes

Looking forward to hearing any answers or comments regarding topic.

Well now i know that lvl 83 mercs have lvl 26 auras and lvl 84 mercs have level 27 auras, but i wanna know how much different is their skill scaling
