May I ask how you got to 60 in 90 minutes SOLO? That sounds very unlikely. I'd even say it's impossible, if you had no one giving you all the waypoints/quests (you can't buy that in the AH, after all).
I was carried by a friend of mine to 60.
The Solo stuff is just above 60. So no grp play bonuses for the whole paragon lvling.
Why do i lvl the same class again? Cause famring at plvl 100 is not rewarding at all anymore xD
THis used to be a challenge to my self to make the game more enjoyable
Ok, that was not clear from your OP (@1-60 carried). The other thing (p100 in 50h) is impressive (though I would never do this). Don't really care for "world record", but at least you have more to offer than certain other streamers
