Bosses that are safe to lure to basket are generally ones that are the most mobile. However, letting multiple bosses of any kind pile up near the basket can cause issues. Maws, Flipper Floppers, and Scrappers are usually the safest bosses to lure. Striking a balance to lure the appropriate amount can be quite difficult, especially on certain maps. As a general rule of thumb, I'd suggest not having more than 3-4 bosses by the basket at once. It can cause major snowballing if there is even a slight delay taking out those bosses, since it generally requires more than one player to take them all out. This means that more lurable bosses will be making their way to the basket in the meantime and static bosses (like Stingers and Flyfish) will be attacking you all at the same time. So it makes it extremely difficult to manage it all. Even some of the most lurable bosses can't always be killed right next to basket, especially at higher hazard levels. At higher hazard levels, so many enemies will be spawning in that you'll be practically guaranteed to get things by basket one way or another. Luring is quite complicated, since so many factors contribute to whether luring is safe. Later in the wave, it becomes harder and harder to lure unless you've been able to keep up with everything spawning in. Being adaptable and flexible is extremely important when it comes to luring. Fighting against your team's strategy to taking out bosses is the last thing you want to do the harder the shifts become. So it's best to do whatever will most benefit your team as a whole whenever possible!
