I haven't played hardcoe mode yet, but I don't know if I would want Boone with me.
He might kill some weaker, unarmored targets, but the ones that actually have some meddle to them kick his ass pretty quickly. He would have died 1000 times over if I was in hardcoe.
I hear you. I said the same thing to myself my first play through (not on hardcoe). He got knocked "unconscious" countless times.
BTW, I don't get the complaint that hardcoe isn't "hardcoe". I got jumped by raider types in that little canyon outside of Nipton (level 4 ish, just started 2nd play through). After dying once (got pwnd by a landmine) I fought through it but with a crippled leg, two crippled arms and a concussion. It was pretty funny watching the character limp and lurch Quasimodo style with badly blurred vision all the way to Novac.
That said think I'll leave Boone in Novac. Or pick him as a companion then have him "wait" in my safe house (like the spotter perk).
