You can always pick a martial class then pick angel/lich? My first lich playthrough was an invulnarable rager that stacked -\DR. Made hell of tank with OK damage capabilities.
Also my Azata was Mad Dog/Gendarme, had really fun with it even with buggy charge at the release.
can you stack good enough dr?
Yeah, if I remember right I was near 30 when entering Midnight Fane for the first time. Also full immune to sneak attacks and critical strikes. Also a sword and board build with lots of attacks (including a powerful headbut from demonic way mythic) that heal very well with vampiric blade.
Effectively "soloed" act 4 and 5. Only got 2 buffbots with me, skeletal bard and Nenio.
