Kogmaw or tristana

Im a kogmaw main now i would not be saying this if there was somthing wrong but we all know what kogmaw is known for his w and his ult and as for trist its her jump gernade reset with kills/assits now here is the problem kogmaws q is pretty much useless late game since it only targets one person and if he gets caught out he is screwed now with trist i did the math and trist q does MORE increased attack speed than kogmaws now i know what ur thinking but kogmaw gets the range increase but so does trist passive per lvl in fact her range exceeds kogmaws w late game so its said to saw trist is a better kogmaw but im still sticking with kogmaw but maybe change his q maybe make it where he can A escape or B make it a different move but what i think kogmaw has better than trist is the ult kogs ult is so good
