I suck at pvp so meh, not sure if should even post..but..
How would one rate the players? Technically, everyone would probably lose against a gm's ban wand or etc. But many would win against an ungeared player, or a low leveled one. It's personal opinion, and saying that there are worse players, better players, or top players, is a matter of opinion and comparison.
Against a gm, top player would prolly lose.
Against a low level, a high level would probably win.
Against a player with very good gear, etc, a moderately geared player could lose.
If one person believes themselves to be a better player than someone else, who is a random, other person to say whether he is or not? He could be nicer than the other, stronger, etc...
It would be incredibly hard to determine who exactly are "worse players", since everybody would have their own opinions (

pretty sure there is a bit of hate at times too. or more than a bit).
Everybody who enters such tournaments would think that they were good at it, or decent, etc.
If you needed to be super good at pvp by donating all your time to it, not everybody here would actually have time for that-and just to enter one of those tournaments.
I just saying here, but I say no. D':
