there were many occasions that ppl tried to pvp on hell diff ? and quess what, normal it was..
mostly due to rezist where the soso had more advantage on hell diff, and ppl just stacked more charms etc. what was annoying or something .. and necro walls ? dont remember, was so long time ago .. normal made it pretty "balanced" comparing to hell..
in d3 there is no such thing, the main thing is loh/ll nerf .. but maybe in the future ppl will find out more..
