Suggestions for my roster

Forewarning - this is my first fantasy league ever

After managing to scoop up 3 Fnatic players and the Fnatic team during week 2 or 3 (Steelback, Febiven, and Reignover), I have come to an issue with my top lane pick (Dyrus - TSM) and my support (Xpecial - Team Liquid). Fnatic has been bringing in the points for me but I have continued to see problems with these two as far as points per week goes. I dropped my other mid laner as I see Fnatic as a solid team throughout, and with Forg1vengre in my Flex position I dropped 2nd mid laner I drafted (Fenix - Team Liquid) and added Cabochard from Gambit as well as dropping Xpecial for Bunny Fufuu as well.

Now I am unsure if I should stick with Dyrus going into week 6 or switch him for Cabochard. I notice that TSM is seemingly going to have an easier week compared to Gambit but Dyrus still seems to under perform as far as points go, this goes for Vander, my other support, and Bunny Fufuu. I would appreciate any feedback because damnit I'm trying to win haha.

Note - Going to try and add a picture so everyone can get a better visual of what I have to play with.
