You can bait, but make sure you make verbal agreements with your team. Stuff like "let's peek together" or "go in and I will trade you" and every time call nice try or something positive when they actually listen to you. Teamwork is crucial and even minor things like these will win games. Either play a complete anchor on a site or as you said, play positions with high impact.
Switch up playstyles, like you can be aggressive as CT with your team in mid, pushing two people with flashbangs over connector, or double peek into palace from A. Stuff like this. Make agreements with your team and stay positive.
