Many people play tibia because of the pvp-feeling and the best pvp-feeling you get is from versions below 8.0 in my and many others opinion. There is a simple reason: pvp is alot more skill dependant without hotkeys. With hotkeys all you need is a good commander and good teamwork, individual skill is an insignificant factor.why should people play 7.72?
it's old, there are nearly no spells, hunting areas, quests.. PoI, azerus, demon oak and a lot of other great quests which people love are missing.
Knights and pallys are useless, only sorcs and druids are ruling.
And if you have "high exp" it will be more unbalanced... thats my opinion about "oldschool servers". Most players are too lazy to play it without rune hotkeys..
