@Kenji-Kunn The low-profile "nerf" wasn't a nerf, it was a change to rebalance the legends based on their hitbox sizes. The 2 nerfs to her abilities this time around were a bit excessive, but I do think 1 of those changes were necessary to help bring further balance to her strong abilities.
The faster revive buff to Gibby was not necessary, as he already has strong abilities. Gibby is very strong and useful now, but I think it is hard to argue that single change all of a sudden made him the MOST OP LEGEND EVER like everyone is screaming. However, what I think they should do to balance him out more is decrease the gun shield by 50%.
As for lifeline, her passive ability of faster consumable use is arguably still the best passive in the game. But she has been overshadowed by Gibby now, so I think a good solution to make her a viable legend would be to return the chance of spawning gold items in her care package drops like in S1.
