While I find this game to be a lot of fun and extremely visually appealing, the cross-ark transfers with no limitations and no cost completely wreck any balance and eliminate fair-play. Starting players have no defense against a high power group suddenly spawning in and destroying everything.
If people really want to grief others so badly, they should be required to level on the server they wish to troll/grief on or have to pay to transfer from server to server and be limited to how often they can transfer/re-transfer. They should also be limited to their personal inventory as to what they can bring with them. That would go a long way towards balancing out the problem that Studio Wildcard created when they enabled free and unlimited server transfers.
I'm fine with PvP, but I shouldn't be forced to resort to running a private server to avoid griefing, hacking, and lethargic involvement from admins.
