@E9ine_AC Horizon is likely receiving a nerf to her tactical so her success won't be ignored.
I personally find Wraith extremely boring. Her personality and abilities put me to sleep. Wattson has the most loveable personality to me and I love Gibraltar and Rampart's initial abilities.
All the Legends feel unique and interesting so she can't be popular for that reason. There are 3 possibilities that I can see.
#1 She's chosen because the best players use her so casual players flock to her as well. Happens in every game.
#2 She simply has an easier time winning.
#3 She was one of 3 Legends whose abilities felt smooth since apex began so she was often picked. Now players just feel comfortable with her.
I think @E9ine_AC you'd mostly agree with #3 while a lot of players support #2. Her popularity can be explained by reasons #1 and #3 but not her win rate.
I haven't seem you suggest this but "Wraith players are just better than other Legend players" is a crap reason that nobody is willing to support. Her success has to be explained some how.
