How to handle this situation?

why the possessive pronoun?

WELL... um... Lucidity boots aren't the greatest first rush, but they aren't the most horrible item to build on an adc (dem cooldowns, ya know). Though those would be much more useful on champions like Vayne (who'd probably use greaves better anyway), Graves, and Ezreal.

Though, to handle the situation... just build to poke fun at them or just mute them and ignore them. If someone's terrible at the game and tries to vent their rage at you, it's best to ignore it.

as a support main I just try to accept the adc as a family member. makes me protect them more

And there's something wrong with that? Ezreal often builds then, so does Lucian... Corki is often built with Sorc Shoes. So why can't people build outside of the "meta" with other ADCs? Jinx for one already has an attack speed steroid in her Q, so it's not like she needs that early on.

ok lets think about this. EZ does build them, but what does he build first? Tear or lucidity boots?

If the jinx proved to have any skill at all it would have been different. When you end up going 3/14 I question if they really know how to play the game while they call me a trash support. I know you might think she dies 14 times so i must have sucked at protecting her, but let me assure you, i did my very best, she was just that bad.
