1. Yeah. Make something unique - that's what opentibia needs. However, if you want more players do teleport ot as in post above, but put some known maps or at least their parts like yur, evo, etc - it will be their choice where they want to play - as in rl tibia you may choose old-styled thais or surrounded by hunting places yalahar. Keep in mind that there may/will be uid/scripts conflict so change storages/uids.
2. STOP THE FUCK CALLING IT DONATION AND

3. You can't have high exp server and cool pvp with 140-180 levels. That's your choice what you choose. My idea: Keep stages from 225x on low levels to 3x on high levels and create stronger spells for every vocation, but please don't do combo spells like throwing animation+ue+some energy and damage 1000000 - it really breaks fun at least for me. Just make 'exevo gran mas san' for rp, exevo max vis hur for ms, exura gran sio for ed, etc. -remember about pvp balance. There shouldn't be any border. Players should meet monsters which can't be killed on 2000 level, but can be on 2500(same as on low levels you can't fight with juggernaut on 20 level). Keep leveldoors with minlevel like 4200 to prevent 1500 leveled players from death on powerful creatures.
That's my unrealized yet idea of high level fair pvp world.
