Snipers tend to be increadibly obnoxious, if theyre not sniper its
OMG NOOB LET ME SNIPE
They concentrate on killing other snipers rather than useful things to kill because they dare not die, they take nades, and will sit on it and push people away with charged shots if you try and take them.
And start getting in a hissy fit when you spend the game hunting them on the balcony
Of course there are exceptions but in my vast experience this is what i find happens
