Hi.
About exp, i think now its time to rise exp for first ~50 lvl little, low exp and hight top scare off new people, when u see that TOP and ur exp in loren ~50-100 i dont think what anyone wants to continue.
Wizard Ring, on every invasion i kill 4-8 orcs and find only one WW and i use him only on hollidays coz i dont know when i find another, but if i find i cant get him coz ww ring cant dropped down( i tell about that ).
Jwl of Chaos, its rly big drop, need a little decrease it.
Feather/Crest, i think every time when we past stage need to rise a little drop, TOP charters dont win more but beginners will be a little easier.
