At the end of the day, Warhammer is about WAR! PvP with small PvE elements is exactly how I imagine a Warhammer game. The Tyranids will provide a good PvE enemy.
I think PvE is going to tie into the game a lot. Nids won't be in just one area and you can go there to kill them. Races that are doing too good are going to be attacked by the nids and are going to have to do something or lose ground to them.
PvP is pvp no need to go into it to much as it is going the be the main dish. But dynamic random attacks by tyranids for example would be a cool thing to happen, your out fighting and your losing , then all of an sudden tyranid holes pop up and they spawn turning the tide back into your favour, or they could also spawn helping the already wining side it is random for example. A second thing that would be nice is to have some sort of raid moments, where one could jump in and gain some rewards against the pve mobs, maybe if i do enough raids and complete the objectives we get help from the pve NPC mobs by having them spawn closer to our enemies when in battle, in a dynamic way, of course if there are no enemies left they attack you instead they are a third party of course. So an integration where pve can affect pvp, call it "Faction luck".
Your faces when nids take over bases, convert them to hives, which make more nids that assault other bases, and take over the entire map while everyone's asleep.
Sorry I should be more specific. Do you feel that the PvE should be included but be SEPARATE from the PvP entirely (As in I can't interrupt the PvEing of other factions to gain a tactical advantage).
In a word, no. I think PvE should be used to enhance the PvP aspect of the game, not to avoid it entirely.
I agree, It should be an optional extra that you can do to gain benefit but shouldn't be supported and expanded as it's own playstyle. It doesn't really fit well and i feel would detract immensely from the PvP gameplay.
Guys who voted for PVP, I think you are all a bit scared of getting eaten by some ugly Nid (not to get confused, I voted for PVP aswell )
