PvP is divided into smaller brackets now.
x0 to x4 -and- x5 to x9.

If your toons are 24th, 29th, 34th, 39th, etc...
You will be extremely strong, even more so because of boxing.
If you can win more than half of the BG's, that is a decent leveling method too.
And supplements your other leveling.

Plus, if you have any interest in PvP, being able to buy a couple of pvp items at 85th immediately is decent.
Even if you only plan on PvE stuff, the 2 minute trinket is worth having.
