Restricting high-level players from the mode is probably not something they would even consider. Strictly speaking, they have as much right to bots as any of us.
Stricter sbmm is an impossibility. If they could do it they already would have. And if they did then the high-level players would just saddle up in their secondaries and demolish the entire lobby just the same.
The only way to keep the mode from turning into the pubs-style **bleep** hole that it's already become is to put a bots-only button in the lobby, allowing every single player to opt out of live enemies in a mode that should never have had them to begin with. And it should be two buttons: one that allows the player to choose bot-only enemies, and the other to choose bot-only teammates.
Respawn: Get live players out of my PvE game mode!
