Don’t let them fool you, if you are not interested in overwhelming / outnumbering people or being outnumbered / overwhelmed then PVE servers are 100% acceptable. The reality is that PVP servers are for the most part dominated by one side. If you want to experience wpvp the wpvp on pve servers is typically way more fair as both sides are looking for PVP and zerging deters the other side from pvping.
On pvp servers typically the way it works is: One side has an overwhelming force, to fight it you bring close to even numbers. If your side wins, the other side will literally disappear and run from any fight until they can again overwhelm what was an even fight, or they just dont show up again.
So you spent 20+ mins prepping to go at their zerg, for about a 30 sec fight.
PVP servers have calmed down a bit, but up until recently I could count on one hand the amount of 1v1s that didn’t instantly become a 3v1 or worse.
The reality is that people that flag on PVE servers get more real PVP and are actually way less carebear than any one that rolls the overwhelming faction on a PVP server.
