1 - First of all, it is a PvP focused game, but it's more like ArcheAge than BDO as far as I can tell.
2 - The world map is akin to FFXIV without being a true "open world" map but several large maps interconnected by long narrow paths.
3 - Fixed economy / No player trading is probably one of the worst things ever introduced to MMO's by BDO.
4 - B2P / Convenience Subscription / Cash Shop ( Still waiting to see just exactly what is offered in cash shop but rumors are, it's not pretty )
5 - No fishing? Granted most of BDO's tradeskill features could be done AFK, it still added flavor to the game for those who enjoyed it.
In regards to the cash shop, just be warned that even some of the Emissaries that went to the press release, played the game and asked them questions couldn't get a clear answer. From what I've seen and heard, it's as bad if not worse than BDO in that regard.
