So, it used to keep you in the same bracket back in the day, even if you levelled-
I distinctly remember hitting level 20 from 19, learning my mount, and being a level 20 with a mount in a 10-19 bracket battleground, with players laughing and saying “What the hell” and whatnot, back in the day.
It doesn’t do this anymore- if you level, you are kicked out of PvP queue generally.
Maybe that’s only from hitting a new level bracket, as in every 10 levels or so, but idk, it’s been forever since I’ve levelled an alt and done lower lvl bgs.
PvP itself used to be a great way to level and grind honor, too.
But it’s since been nerfed repeatedly over the years, and also people grouping with their higher lvl friends in low lvl PvP (while being fully maxxed out and geared) also ruined it.
