Been trying to get info on this as its hard to find out.
Turns out, even if you hit 60… you lose your soul of iron buff along with any other HC related buffs when dying.
Blizzard come on, let us keep that buff if we hit 60 and move to PVE as a badge of honour.
Seems like such a huge oversight in a game all about showing off our shiny characters.
Because keeping a character alive is not just have been… a levelling from 1 to 60… a game, challenges continues…
Like in any other game wich has hardcore aspect… you die and your toon is dead simple as that.
Yes you are dead on HC, but you live on with your character on normal server.
Why not be able keep the soul of iron buff showcasing your achievements as a badge of honour.
