I am just the opposite. Open world zek pvp is almost always decided by who exploits the most. Zone camping, corpse camping, exploiting mechanics or just zerging. Actual ability to play is almost never a determining factor.All depends on what kind of PVP you enjoy,
Personally I'll take Zek (any of them ) and Vanguard PVP over any "designed" PVP.
Designed PVP usually means instanced , balanced crap that is boring to me. The idea of doing PVE while always having to look over your shoulders and protect your group makes PVE x1000 times more fun. While at the same time being able to gank someone who took your camp , kill every gnome you see , and so on is the fun kind of pvp. Never knowing when it will happen nor from where or who. No to little rails in PVP just as PVE should be also.
Capture the flag,10 on 10, in a colorful little instanced zone is boring as all hell on the other hand.
Basically I enjoy PVE with the PVP turned on and nothing else changed. I don't really call them PVP games , just PVP is occurring in the midst of PVE.
Separating them takes away the fun to me.
Once in a blue moon you end up with an epic war but for the most part it comes down to who exploits first and most often.
