I can't believe the difficulty jump from Act I to Act II in Inferno. My god. I breezed through Act I and even upgraded a few pieces of gear heading into Act II. So hard. The champ packs have the most ridiculous affixes and are almost impossible to kite away from white mobs. I can handle white mobs unless there's 5 wasps sniping with their little bugs but the elites are really, really tough. I don't know how much I can reasonably expect to upgrade my gear either. 71% reduction from armor, 64% resist all, 35% dodge, 19% block, 35k health, 17k dps. I had a little bit more success when I revamped my skills to all survivability, but I can't imagine if the jump to Act III is the same how I'll ever have the time to do it.
The first wasp champions I encountered were a 4 pack with fire chains, jailer, mortar, desecrator. Forget about it. The white wasps hit me for 25% of my health if they hit with their bugs. There is literally no way to kill that group of champ wasps. I had to skip them.
