Ideas on where to nerf Irelia's too strong lategame

Her damage numbers are pretty much ok(mostly) so here are a couple places where irelia's lategame could get nerfed without causing too much of a harm to her already mediocre pre 6 laning phase, i'll also exemplify: -Passive AD scaling per stack (from 2% - 4% (based on level) AD to 1% - 2.5% (based on level) AD) -Q cd( due to her many resets and her usually building a lot of cdr , she could use a higher penalty for failing to get a Q reset ) ( Q cd increased from 12/11/10/9/8 to 11 at all ranks ) -Q mana cost ( from 20 at all ranks to 15/20/25/30/35 ) ( her mana bar is mostly for decoration after getting a saphire crystal ) -Lower Q bonus damage to minions ( from 60% to 30% ) -W Damage reduction values(from 45/50/55/60/65 down to 40/42.5/45/47.5/50 ) ( ap ratio increased from 7% per 100 ap up to 10% per 100 ap ) ( if she wants that sweet sweet damage reduction she'll have to invest in ap ). -E2 cast range ( down to 300 ) ( atm it's completely obnoxious to deal with and extremely easy for her to land ) -The time window in which she can use her E2( from 3.5 seconds down to 2 seconds ) -Ult range ( from 1000 down to 700 ) -Ult slow value ( from 60% to 45% ) -Ult cooldown ( from 120/105/90 up to 150/135/110 ) -Ult damage ( from 125/200/275 down to 125/175/225 )

Reminder that this post just lists some potential ideas of where riot could nerf irelia's lategame in the future and that it is not a "IRELIA OP OMFG SHE HAS TO BE NERFED IN ALL THESE PLACES OR ELSE" , this list just shows some not that harsh(mostly) nerfs that riot may or may not do that they could pick from . So if you were to pick 4 nerfs from this list , which would they be and why ?
