Stalkers in KF3 should be smarter
From all the footage and teasers that have been revealed for KF3, there's one zed that we've yet to see make a return wich is the Stalker. When she does make her grand return, I expect her to behave more like a stealthy assassin this time around.
Instead of treating her like a clot with a gimmick, her pathfinding AI should be massively improved to accomodate for her abilities to lay ambushes on unsuspecting players. To maker her stand out from the other zeds, she should always spawn in the backlines and avoid direct confrontations with the player by hiding behind obstacles to circle them.
She should never run in a beeline to get to the player but instead should try to use the high ground against them by jumping through ceiling vents because one of the main weaknesses of players is that they always forget to look up. She should always take advantage of the maps layout and have you second guessing as to where she is at all times.
