DR, at least normal I haven't touched savage, honestly felt about in line with normal alliance raids difficulty wise to me. Of the Bozja raids only LL really ever gave me any trouble and even then, I think that was largely some bad group luck when I was still learning it.

That's not to say I never died in DR etc, but I die a lot in new alliance raids as well while still learning the mechanics, this didn't really feel any different in that regard.
