exactly, you can avoid PVP 100% in this game if you really dont want it
That is not entirely true, someone can just equip War Banner and attack player without war of flag On.
this isnt entirely true too, as there is a 30 second warmup for "banner of war" for long time now, means if i want to kill someone i need to pop the banner and then wait 30 seconds before i can attack
teleporting away takes only a few seconds with CTRL+H teleport
you have 20 seconds to taunt him before
so if you want to avoid the PVP you just port / go away if someone pops a banner, end of stroy
