Lead Apex Legends game designer Daniel Z. Klein has teased a "spicy buff" for Rampart set to come in a future update.
"It's a bit too early to talk about her spicy buff because we don't yet know if it'll work and if so when we can ship it," Klein responded. "Right now, IF EVERYTHING GOES WELL (which it never does), you can expect it halfway through Season 10. Game dev is hard and takes a long time!"
Rampart can place cover that increases her teammates' damage output, drop her emplaced Minigun Sheila, and benefit from increased magazine capacity and reload speed from LMGs and her Minigun. She's received buffs steadily since her introduction in Season 6, but her abilities have largely remained the same as when she was first launched.
A "spicy buff" could mean a more significant change to her kit than the shuffling around of values. Fans in the Reddit thread theorize automatically firing turrets or a movable Minigun, but Klein remained tightlipped on the subject.
Apex Legends Season 9 kicked off May 9, so the earliest the buff could arrive is Season 10's launch, likely set for Aug. 3.
