If you decides to embrace 1 v 1 in any mmorpg in which balance either on group or smaller scale 3 v 3, then yes.
You mis-understood the purpose of 1 v 1 in mmorpg; it is something a player to embrace to show their uniqueness by doing something that was not design by the devs. (most of people cant function without a healer)
It is not something need to be balance.
Especially you are playing on a job that design purely for group encounter: Holmgang and Shake it Off
Holmgang has near 90% kill rate in the current new mode.
This is something other tanks cant do
While you complains about NF, I think a lot of people also have problem with Warrior's inner release on certain pvp mode where they can lock down the ramp with CC immue.
If you decides to quite PvP for this non-sense reason, cant really help you
