1. The trail monsters leave that has MOLTEN in their name. Their explosion after dying however, CAN be dodged.
2. Plague, just no.
3. Desecrator. Vortex + Molten + Jailer + Desecration anyone?
4. Electrified, it's not that it's painful though.
Stuff that could be Dodged
1. The chains the FIRE CHAINS monsters make(duh) can be dodged, based from my own gameplay, even got 15 Dodge in a Row achievement because of this.
I'm not sure of these 2 but some say they could be dodged, but from my experience, you just can't.
Arcane Sentry and Frozen(I'm leaning towards that this can indeed be dodged, just not 100% sure).
So yeah.. Since monsters with the above affixes if they have those non-dodgeable stuff, Dodge is somewhat negligible but is still a great help.
I could get up to 72% Dodge with crappy stuff, but that's just me and it's tedious to maintain, and is impossible to maintain for a long period of time.
