I am happy that players kind of have a similar view to what I am thinking about. I made a topic about it here: How To Improve The WoW PvP Experience if you want to read my view on it. I totally agree with what you say though on the point where it feels like either you are too strong for your opponents or they are outgearing you. For casual players I do not think that will make them want to stick to pvp.
Sadly I do not think that templating is a good solution either, because then you lose the progression feeling from getting gear. Instead I think they should make the progression like they made it in WoD for example where you geared up slowly with honor and then conquest. I can not remember being completly useless in WoD either but I still had fun gearing up because I did not get oneshot and it did not take ages.
