senna's unbalanced right now on adc partly because of the overwhelming strengh of hexoptics and infinity edge on her, those two items practically triple her damage, riot could reduce her crit % damage down over and over, and at that point, why should her passive give crit? so i came up with an idea.
changes to her passive
senna can no longer crit. instead when she crits she applys ON HIT effects an extra time (q can crit on Main target only)
passive % soul suck damage reduced from 1-10 to 1-5
on sucking a soul out, she applies ON HIT effects 1 extra time
crit chance per 20 mist increased from 10 to 20
q ad damage scaling reduced from 60% to 35% (cz passive 20% ad on hit more dmg yk )
q ad healing scaling increased from 40% to 50%
q now gets it's cooldown reduced whenever she attacks and when she applies an extra on hit with her passive (crit or soul suck)
w ad scaling reduced from 90% to 65%
these changes give her so many more items to work with awhile also reducing her damage she gets from stacking crit items.
the idea is that she builds maybe 1 crit item like rapid firecannon, then other items would be black cleaver (as usual) and maybe muramana or botrk or some other on hit item (yeah muramana has on hit in it)
She could still go adc by going items like kraken slayer first or second, but it would be significantly less oppressive, since later on instead of critting you for 800 damage 1000 units away, she would hit for 350~ deal around 200 extra with kraken slayer and have to kite you between attacks
(right now with senna adc you attack someone twice and they die if you got ie and hexoptics)
