I think sivir is getting behind among the adcs and more behind the champions in general because of the season adc bullying phase. After sivir's w and R nerf her early game was too dependent on her abilities to deal some dmg making her wait for her 2 core items to start dealing dmg (essence reaver for her mana and i.e. For dmg ) but even if her mid to late game is better than her early she still gets behind other adc on late game. 
Zelnick1 votesSivir is definitely lackluster atm, without the ricochet damage she has no relevance early game for pushing towers, and then she just gets completely out-scaled by every single other adc, so it's all for nothing in the end anyway. She's just an adc who deals less damage than a typical adc, except she has a spell shield in place of mobility.
DarkFlameMazter1 votesYep the only reason to play her is cuz she is fun but in utility for wining a game or just helping your team is one of the last picks you need
ReZisT Lust1 votestry to max w instead of q then
Wilbor1 votesas a sivir player, shes not "secret op", but shes" secret VERY strong adc" right now. people just don't know her powerspikes I believe. she stood steadily on 50% win rate in patch 6.24, and now according to op gg she rose to the 7th place (with ziggs in the 1th) leaving adcs like jhin and jinx behind. her late game aoe is insane i can tell u that. her early game is extremley weak and a lot of players can't find the way to play around it. when she gets her 3 core items (ER, PD, IE) good positioning in teamfights with her w is like twitch ult just no cd.

You are right but by the time she gets her 3 core items (expensive af) its usual that other champs will be far ahead so I'm looking for an early buff or just a general buff 😭 I want her to be more umm playable I think than just farm for 30 minutes until the 3 items are build xd

u are right that her "hypercarrying" powerspike is late, with three big items. BUT two things about that:
Sivir is probably the greatest wave clearer in the game, she farms like no other, meaning, that even when shes not fed, or even when behind, she is farming so good that she can get her items in somewhat easier way than others.
and that's about what I said in my last post, about people not really knowing her powerspikes. yes, her big one comes when her 3 items are completed, and she has 70% crit chance, 30% cdr, and lots of damage. BUT, there is one, during the laning phase too. when sivir gets a bf sword she is probably one of the best adcs to combo with a "killing" support - morgana, blitz, thresh, leona etc. not many can give this much of burst damage with q - w+auto reset - aa this early before lvl 6. try to play really deff early, farm to 1300 gold, come back with a bf sword, let morg hit a q, and u gonna get a surprising burst damage.
and btw I didn't even mention that sivir is one of, if not the safest laners of all adcs. not even the ones with mobillity can make me feel safer then sivir. just don't fall for "Spell shield baits" ^^
and Yes, shes an horrible duelist (so as other teamfighting adcs such as jinx minus the passive), and if your team won't group it can get difficult.
King of Demons1 votesShe's a late game champ in a meta that is focused on getting an early lead and finishing in the mid game. Ofc she will feel bad. Buffing her to a state where she is good to pick in such meta will just make her OP once it shifts to a more late game focus again.
