Arena returns this patch. There is an encyclopedia of champion adjustments.
Every single time Briar shows up in the patch notes for her bi-monthly nerf, Riot says "as players continue continue to get better with her", but how? How has the learning curve not been hit among the playerbase on this self-taunting ball of statcheck?
Are players really continuing to improve on the yuumi of bruisers? Are they? What is this hidden tech in her kit that's being mastered after 3 months?
While not mechanically intense like Yasuo, Briar HEAVILY tests a player's decision making. Most of her spells straight up kill her if she uses them incorrectly so there's a lot of mastery to be found in learning when to cast spells and when to hold them.
Additionally, good Briar players have more outplay potential than you'd expect with the E DR + knockback and W Dash.
