Maeve struggles against groups of enemies, so stick close to your team, especially if you are a support, because you can pressure her either fight, where she will most likely lose, or to flee.
Someone recently mentioned that when Ruckus uses his ult he can't move so use Jenos' ult then. Even if you do that it won't kill him since he's a high health tank unless he already has half of his health down. Instead see if your enemies are cornered
