thank you all for your support.If there are guys that just started a rogue or are planning on it here is a advice for those that plan on using crossbow(this is what i did and it worked great):
From lvl 1 to 12~13:
-level as fast as you can;
-only level up rogue and crossbow related skills(both active and passive);
-dont rise any of the dagger skills(both active nor passive);
-dont rise any othe class;
After level 12:
-search for Ong taxi(if you dont have gold you can find guys that plvl for free);
-keep leveling up rogue class;
-you can continue like this until allmost 30;
After level 27~30 as you wish:
-go to downhang and hunt Earth Ghosts near east gate.You can farm alot of gold and items and also level up very nice.
-you can continue like this until level 30-32(if you came here before level 30 of course);
After level 32:
-you can go to Samarkand and hunt Kokoru.You get plenty of exp and good drops.They can be easily be killed.
-you can continue like this until lvl 35.(you also can switch to Ongs)
After level 35:
-you can get Penon plvl and with gap 0 u rocket to lvl 40~42 depending on your pocket
After that i dunno more..Cuz in 4 days i only got to lvl 41.Maybe I will make a complete leveling tutorial for rogues.
But until then Good luck to all rogues in Silkroad,
ROGUE FTW
