I reached level 6 after a long long grind, but it's still shown as level 5 in the comment section.
I also woud like to address the privileges, it takes as long or even longer to get from lvl 5 to level 6 than from 1 to level 5 , but the privileges you get in return are not really appealing. With level 6 one should get at least 1 more power stones a day, only 3% more spirit stones for successfully inviting a friend compared to level 5 is a bit unrewarding.
Lastly, am I server first? Would be sweet if there was an achievement for that or a ranking just like the ranking for contributed spirit stones and power stones to a novel.
