I've never said that. Vanity rewards can easily exist. People flooded the ranked queue in swtor just for a shot at the 1500 rating rancor mount. You don't need gear to incentivise rank. Vanity works just as well. Mounts, pieces of armor with no stats that can be used for glamour, etc...
swtor is going on its 9th tier of pvp gear. So you don't need to tell me about "hard work" as I'm always min/maxed on the highest tier of pvp gear on multiple toons. Even though in reality that hard work is nothing more than grinding, but whatever. All gear does is put me on equal footing with other min/maxed players and lets me absolutely obliterate people with no gear and they could be possibly good players, they could be bad, hell they could be new, but at the end of the day skill had zero play in it, and if its a new player? There's a high chance they will never come back.
So please tell me, what's the point of PvP gear? Because in the years I've been pvping in MMO's with PvP gear I've slowly started to wonder what the point is. Hell, in swtor I'm at the point where I'm gaming the refund system by purchasing low level pvp weapons and then trading them in before the timer runs out to be max geared before I hit level cap on any alts I level because I refuse to queue without pvp gear (by level 54 I usually have 20+ weapons, enough to get completely min/maxed)....that's how bad the disparity is between people with full expertise and people who are just getting bolstered without pvp gear (new players). You get absolutely destroyed.
Why should I even have to go through all that? What's wrong with hitting 55 on an alt and letting skill be the determining factor? Why do I need pvp gear? For what? So I can roflstomp people without it? I'm sick and tired of it. I'd be much happier with a pure bolster system like how it functions in the low levels and just have customizable armor shells or mounts or some other kind of vanity along with the ranking system as forms of "rewards."
No one here has yet to give me a 100% valid reason why we "need" pvp gear outside of being butthurt because they spent time win trading to get their current gear...which is not really a good reason.
