I am not yet on act 4 but my guess is that with my current stats I would need to switch to Force again to avoid being one shotted. Actually its possible that for Act 4 using defensive stats you will need to carry a shield.

Act IV is the same difficulty as Act III. At least, that was my experience. I steamroll Act I in MF gear, steamroll Act II in half MF gear and lose gold at a rate of about 50-75k/hour when doing Act III and IV in my pure set.

Act IV is really only complicated by the monster TYPES. While the act in general hits just as hard as Act III, there are a good number of mobs in there that are inhenently fast or strong or can cast fucking meteor. Getting elite Dark Angels, or swarm spiders with molten, or those fucking octopus pounders can suck ass.

That said, I didn't find a single one of the bosses post-Ghom to be even a remote challenge and one-shot every one of them (save Diablo, obv).

That's a melee standpoint though, of course. So it may not apply to ranged.

dont get bone prisoned

Was expecting a "boned in prison" joke. Disapoint.
