With planetary achievements I feel that the player vs player section should be removed and placed into the pvp section of achievements.
My reason behind this is. As far as I've seen people wont have these achievements unless they organise it.
Also many people who like to go for achievements may not be interested in the pvp side.
I can see this as being beneficial as it would allow people get those final elusive planetary achievements without having to try to organise the pvp end.
