by the way rank 30 in 4 days may be possible.
I'm almost rank 18 marauder but im also rank 14 wood, rank 14 botany, and rank 7 leather.
I'm phys level 23
I've got enough mats to push wood to 20 and leather to 13-15, mainly because ive been farming a lot.
If i woulden't have farmed or done botany and just focused on marauder id prob be around 25 (i was 20ish in the open beta so i know how much time it takes). If I could pull off 25 in 4 days while sleeping and occasionally going out, im sure if 2 ppl took turns playing (playing 24/7) they could pull off rank 30. However I am rank 17 atm and in "surplus" mode already, so I could see that as a barrier. On the other hand ive been in surplus mode for over 11000 rank exp and it hasnt really made me feel like im levelling slower, so who knows how that works.
So what im sayin is if someone got the game on tuesday when servers went up and played 24/7 and the surplus didnt exist or is glitched, rank 30 is believable.
