Damn you are getting almost 1k main stat from one item. You could easily see characters having like 8k main stat in the expansion. DPS numbers will be crossing 7 maybe even 8 figures!
I'm thinking we'll see a similar jump in the exp/hour rates.
Combine all these factors:
- higher damage
- faster move speed from paragon points, allowing higher damage gear instead if it doesn't stack
- 4 passives, and new ones like the WD passive for 5 minute DoTs
- "build-enabling legendaries", all those crazy new affixes
- level 70 enemies (higher exp per kill)
- Adventure Mode mega-runs cherry picking the best spots among all 5 acts
- easier to gear up thanks to smart drops and the mystic.
I've been chipping away at continuing paragon levelling on a third 100 but it feels like such a waste when the same experience can probably be obtained 10-20x faster once the expansion arrives! Still, it's a bit of a head start.
