Not really, basically what @
Mazz do involves little to no planning or anything, or crazy gear (at least on my end). Basically we just throw some common gear in storage the night before. For me this is just evo rings, a mask, a pac, all stat earrings and a couple other things based on whatever class it is, for Hayato, I didn't really have any low level str gear so what I listed above was it.
The trick is to log in as soon as the patch goes live, or close to it. The earlier the better. Make your character, jump on your other link mules and link whatever you want to, set up your character cards for whatever class it is, get a 2x card and use an HS mule. Also, if the class offers 1.5x coupons every 5 levels from 50-100, that helps a ton too.
90% we forget to do something, DC a bunch, get locked out of our characters for a bit and whatever else usually happens when a patch goes live.
Honestly, we could do this much faster, but we usually party together until about 70, until we can solo an Aliens 6 map.
We got pretty lucky with Hayato, we each only DCed once, and we both leveled to 100 after about 1h 40 minutes! Definately one of the funnest/fastest despite no 1.5x coupons.
We've pretty much been doing this since Legends.
