It's been a few months since I've played. I have a Barb 42paragon. I've heard about all these updates and nerfs and this and that.
My question is what is the fastest paragon xp now? Are Alkaizer runs still the way to go? Or is there another method thats faster now?
You should start worrying about what's the fastest route until 1.0.8 patch hits sometime next week or the week after that. With the new monster density changes (to mp1 and above) new routes will be better than right now, it's basically waste of time playing at the moment.
