In my opinion i believe that the most people Nowadays looking for a server between 250-500 exp rate Maximum.
Now as for the custom/non-custom..OF COURSE They prefer non-custom and no tattos or any bonus items etc.
Would be perfect to create a pvp server like 500 exp rate,maximum enchant like between 10-12. Medium farm(i mean not 5 mobs and your full).
Normal scrolls,Blessed scrolls etc..would like to be like Normal scrolls rate:60% Blessed scrols rate: 80%(or so..)
And many more stuffs like the old L][ I used to know before 5 years.
