An MMORPG have always been a game wich costs some time. The nerds are highlvl in a few days/weeks and those wich just play for fun are highlvls a few weeks later. I think a pServer with 50x exp rates would be far too much(In my opinion). Sure, there would be the possibillity for a PvP server with higher rates but the "nerds" (like 26/8 handgrinding :P. Sure, most of them are botters) would be still superior, because of Sun-farming etc.
there should be a PvP server with same levels and same equipment, so it'd become a challenge for the builds and skills in usin them.
that's my opinion so far. 20x rates are far enough. And if there's a higher droprate of gold etc. the prices would just grow extremely. (Like ecSro weap. elixir 4 mill e.g.)
