no. ancients give a certain amount of exp (based on difficulty).

but that exp is not taxed by your lvl exp reduction. so save them till you're 90. (you'll get a few mill = 10-20 baal runs )

u will get shit exp from both =/

but its like | | from nm i'd wait till like lvl 95 or if ur going to lvl 99 wait till lvl 98

etc it isnt much but that those lvls its so hard to gain xp they actually help

Nope, you won't get a full level from killing normal or nightmare ancients at a really high level.

if i did..
people will lvl to like 95 +

and do ancients

like lvl 96 and do 3 ancients

thats 99.

no but will get a little exp from them

no for each of them its a set amount of exp
