I had to repost this very interesting statistic about how long it takes to reach level 50 in Tribes Ascend, sourced from the Hi Rez Forums.
HiRezScott states: “15 players have reached level 50 so far. On average it took you all 970 hours of game time to reach, though some took longer than others.
Fun Fact: Pathfinder was by far the most played class among you guys, though there is a Sentinel, Juggernaut, and Infiltrator dedicated among the 50′s.
Another Fun Fact: One player in particular has almost played enough to have reached 50 twice. We are a little worried about him.”
I’m guessing he’s referring to AnarchyAo, who seems to be online pretty much always and was the first person ever to reach level 50.
