I bloody love the boss fights in these games, but once they're done, they're done (until NG+). So I reckon From should give us the options of fighting the bosses in isolation. I envision something like a gravestone in Bloodborne or whatever facilitates hub menus in Dark Souls (I'm just getting back into 1 after my fourth attempt in 6 years), and just a list of bosses in their arenas to fight. I reckon they should give you like 10% of their usual Echoes/Souls, or some vastly reduced number so they're not worth grinding, if any at all. Whaddaya think?
