I honestly don't even believe that will be an issue. One of the reasons I am excited for this game is because ZOS is trying to make PvP and PvE seamless. There won't be different armor sets for both game types and combat is ideally going to work the same way in both disciplines. ZOS has been working really hard with their AI to make NPCs work strategically and as a unit in ways that resembles players. If they are actually able to make this a reality, balancing the two will be much easier as the differences between PvE and PvP will almost be eliminated. We'll have to see if they can turn their rhetoric into reality, but balancing could very well be easier than in most current generation MMOs.
Certainly if they can make them more seamless compared to other mmos, then yes, I can not see much of an issue with balancing between the two game types. Will be good to find out more specifics, in time.
i think servers are balance enought, i mean if you go to a PVP sever you basically know what your getting yourself into...
But for ganking thats always a problem, maybe limit ganking and add a debuff or informous rep if the player ganks too much or too harshly
Certainly, if you're going to be on a PVP server then you know what to expect. My point was not in regards to that. My point was in regards to balancing between both PVE & PVP. So, if you are on a PVE server (assuming there will be server types based on PVE & PVP rulesets) and balancing happens to bring an ability into balance with other abilities for PVP it may very well reduce the effectiveness of said ability in a PVE environment. Again I am assuming there will be PVE servers with the option to PVP.
As for ganking, in my opinion only limited restrictions can really be implemented like having safe zones for respawning. If you are out the world on PVP server or in a PVP zone, gank or be ganked. It's the nature of the beast.
