its just that gambit plays the same everytime against all but the others lose patience and give gambit a 5v3 kinda scenario which is easy to enter any site with low time but envy are just so patient and not giving away anything for gmb to play with..so gmb is failing
They are giving Envy way too much space. I mean that's kind of Gambit's playstyle just wait in spawn and go in last second, but its so risky against Envy who reads teams really well.
