TibiaWR, 2 things. One, I think you have a great idea going but I think if you want a non-pvp server it should be old school. Many people want to play a good RPG server that can't be overran by a bunch of botters and what not. So I think first you should get a 7.4~7.72 server that is non-pvp. and for rates, I think it should be Exp - 2~3x, Skills - 2.5~3.5x, Magic - 2x, Loot - 2~3x so that everything is a challenge and people must work together instead of being able to do things solo. Old school tibia is much more community dependent than new tibia. Everything is too easy in 8.x+ So, go oldschool please. Takes more skill. And if you need some ideas, play Eliteots for a little, they have great systems and what not. Their party exp bonus is the greatest this I've seen in an OT in a long time.
Edit: Just my opinions.
