He has a good early poke but late game his damage/presence im tram fight doesnt compare to other carrys poke and composition

Play Jayce as an ADC OP, he doesn't have AD ratios lower than 1.0. Highest goes up to 1.7.

No she doesn't fall behind, she actually has serious damage. Harrier is a ridiculous on-hit bonus, it does her total AD + base damage + half of her bonus AD (x1.5 basically). All of her abilities scale on AD, and she has a full moveset of either steroids or damage abilities, which is only shared by Draven. Not to mentin Valor has a permanent 80% AS bonus. Quinn does ridiculous damage.

I respect ur opinion is just my way of lookinh the things dont get me wrong

You have to center around using the blight stacks. Varus isnt a ''right-click and win carry''. He is hard to manage and hard to keep alive, but is a middle point between KogMaw and Vayne, and exceels with the right team composition, kinda like Kog. If he has a support that can keep someone cc'ed enough for Varus to do his combo, Varus will burn anyone. Also, try to play him AP/AS with hybrid masteries and BotRK, its an actually pretty good counter to health stacking, but does not show its power until mid/lategame.

Shes a great adc i have done like 4 quadra and a few triple with her but only when i have farm cuz dont get to kill

That is how an adc is SUPPOSED to work, EVERY adc needs kills and farm to be good.

Yes but for me to kill need craZy farm. I can freeze lane but i cant get kills in lane phase

Considering that the early brust from her passive and her earlygame duelling strength against other ad carries is superb due to her blind, that is probably rather you lacking than the champ.

It's 65% bonus AD, not total AD.
