7 days 8 hours and level 60 done on Druid, Horde PvE. Not the fastest, not the slowest, without RXP 
Leveling was mostly fine, if quests aligned it was quite quick. Had to drop only a few quests, and didnāt even do most of STV. I was like 10-15 levels behind the fastest levelers and 10+ levels ahead of the leveling wave so usually it was pretty good mob count-wise.
Now to do remaining quests for bonus gold, get 60 mount, and start playing the market. Skinning/Mining now, will have to switch profession slowly, likely herb/alch/fish standard.
For now, I mostly played as a tank in instances, only 2-3 as a healer while leveling and 2 healer UBRS runs 
Typical lack of tanks outside of the very āend gameā.
The older Census posted on Reddit showed a bit over 20K characters on the Horde PvE side. The one from yesterday is almost 17K. Population drop over time is to be expected. Right now the leveling wave peak is 30-40 level range, while the ātailā of 10-20 is still there albeit low - you can start and pick up for now.
Iāll do some raids, but without months-long ācommitmentā
