The last area (It think) is level 45

So if you are blasting through the story and not doing much side content…stand by for a middle finger from Blizzard by being underleveld when most of the game has scaling.

I did only the main story quests and got there at lvl 37 and completed the game at lvl 39 solo on WT2 as a Flurry/Poison Rogue.

Finished at 42 on sorc. Did boss at 44 in capstone.

Want a cookie? Also…rogue.

Sure. Where is that middle finger btw?

I’m level level 31 and I’m just now getting to the Yelesna mines, after I help the barbarians of course. I should be level 50 by the time I finish act 1.

I finished the campaign by level 41 on a rogue. Ranged build, too. Not Twisting Blades.
Before you say “rogue” as if the class is OP, I was forced to change to Twisting Blades for WT3. The build is op, not the class. A couple of my friends have done similar on both Sorc and Necro.
