Level and Rank:
Max level: 300
Max rank: 8 (1+7)
PVP:
1 vs 1
Arena:
team vs team
union vs union
Melee
Dungeons:
Number of lv280-300 dungeon: 4
Max entering times per day: 5
Timetable:
Cbt2: 19/10/2015 - 23/11/2015
Cbt3: no cbt3
Obt: 20/1/2016 -
If you promise not to brag about this later, I will believe you for now. T:
I agree with everything except for the max level/rank.
In my opinion there won’t be a max level, because to reach it you have to grind for months like in the old mmo style!
Timetable:
Cbt2: 19/10/2015 - 23/11/2015
Cbt3: no cbt3
Obt: 20/1/2016
I like these dates 
I’ve seen the new map, my gosh it goes until 280+ 
that’s a lot of time investment
Ahahahahaha
No matter what the max. level is, nobody will reach it except for that 1 party who wasted their time doing nothing but grind 24/7 for the entire month to rush to the maximum, draining their own fun at the game away in the process faster than all of the American oil pumps could drain the Iraqi earth layers dry.
Max entering times per day (for dungeons)? No! pls No! =(
Man people sure are scarred from the first international CBT and its exp rates!!
Don’t worry buddy, if there is a beta with level 300 content that means IMC will want players give feedback of that level 300 content. And that would only happen if they level up. Higher exp rates are to be expected.
I predict a better translation compared to iCBT1.
I see me in your post.
I actually enjoyed the exp rates of the first iCBT.
I’m just voicing my honest opinion.
It would be great for your predictions.
lol
