Actually I understand ranks as a way, how to tell how long is that viewer with you.. Dude can spend all his points, but being a corporal means he's longer with you than some private, also with 0 points
Both got zero points, second does have much more xp..
Also, do you guys prefer to show ranks or hours ?
Me, personally, ranks, because hours, atleast for me:
I am a newcomer, I just started getting xp/points and I see someone with I dunno, 500+ hours.. = OMG How am I gonna compete to that ? I am out
Rank ? Noone's rly know how many hours exactly(!) are they missing till levelup, so it's not "I am gonna stay here 15 more minutes till I get the level, but I'll just stay here, getting xp.."
Does it make sense ?
