Ok thanks for the quick response
Firstoff you might want to change up your weapons for Clam Blitz Custom dulies aren't too bad but all the other weapons you use are long range slow firerate (or chargetime).
Most players run dive weapon like rollers and brushes
In terms of weapons for support my go to anchor weapon for CB is the vanilla exsplosher mainly for coverage (also cuz there is a tech that lets you just about 1 shot an enemy player)
As an anchor obj player here are a few key facts I have taken
-Be unpredictable in your pushes, in game modes like rainmaker player have the tendency to stall for looking time to push...but you can honestly mess up an enemy's positioning you make a push when they are not expecting it
-Also pay attention to what your teammates are running and how they play if they focus objective then take care handle map control, if they have both covered push back the enemy team
***Most importantly analyze how the enemy team is playing
For example: An attacker will always flank and attempt to take out anchor 1st
Players who play chargers or splatling are likely gonna get targeted often, constantly be moving change up positions look for angle the enemy might not expect, play around objective if you can
*not neccesarily on objective so you can retreat if needed and give teammates a safe place to land
Most players especially those in upper ranks are so used to playing a certain way it is almost subconscious in the decisions they will make and the habits in their playstyle.
If you can find the pattern you can figure out how use it to be unpredictable and use it to your advantage.
I did make a thread about this awhile back called: player archtupes in Splatoon it give a generalized look certaib categories most players fall into
