imo it should be entirely 7.4 but on the 7.7(2?) client. the only change that really should be made to 7.4 is that pyramids should be PZ. if it were up to me there'd be no premmy system; but if you have to earn money from it then the premmy system should be as it was in real tibia (7.4). also think it should have the 7.4 map. (just cut out poi and hydras it shouldn't be so difficult^^)
no depot on rook, lighthack command, disappearing vials, shortened djinn quest etcetc.
keep the bot detection if it actually works well though =p
