It suits the system better. You're fighting over territory, indirectly or directly should'nt matter, it should be confined to open due to its inherently competitive nature.Combat orientated players can have as much PvP as they want with others who wish to participate.
For as long as the more combat orientated players have been asking for changes to suit them, there has been a push back from those not interested in PvP.
Personally, I want to see alliances and mercenaries and players actually working together to achieve goals. PvPers and PvEers, IE; cohesive faction play.
And as for the latter point, like i have mentioned before, ganking is mostly a symptom of there being a lack of content supporting PvP. Most gankers, if not all of them will happily fight other gankers. If there was actual content for us to be involved with, IE; fighting for powers in cohesive units, blockading systems, taking on player defence forces in systems our faction wanted to push, defending those who do less direct activites to push powers, etc, then you would see random ganking all but disappear.
There is a fundamental disconnect of understanding between the two groups. One expects us all to be unhinged psychopaths who only want to ruin others day, the other rolls with it because they have nothing better to do and no content that supports them, and thusly there is endless perpetuating the negative aspects of the PvP vs PvE argument. Slapping everyone in the same mode with common goals goes a long way to both fix and permanently eliminate that perpetuation.
