Sure, she's got a lot of power, if used right. Minimal cooldowns at max rank with 45% CDR allows for pretty high spam of abilities, good range, a hard cc spell, and a lot of deletion potential. She kills squishes she can get the drop on fairly easily…
…Just like every single assassin. Which she is. She's a primary mage, sure, but secondary assassin. She has mobility, damage, and sustain. Not unlike

…And I'm not even halfway through the alphabet.
Her wave clear? Barely enough to kill caster minions with a rank 5 Q with
, takes a Q and a W to kill melee minions. This, compared to…say...
, who can take out ~90% of a wave's health with a single E (OHKOing casters, almost killing melees, and leaving cannons at ~50%).
She's a safe pick, sure. Against non-burst, non-tank champs. And she's good against tanks in end-game, a rather important thing, considering how OP a lot of tanks can be, with her true damage Q and ability to stay tauntingly out of their range. But she dies to (competent) assassins (might explain why you have so much issue - you're either playing the totally wrong class of champions, or you aren't competent), and anyone that can close the gap (assuming you can actually dodge her charm - not that hard, considering that I, a bronze one player who hasn't even been playing for a full year - can either a) dodge it, or b) block it with a shield/minion most of the time) and kill her before she can really react.
And, really, she has nothing in her kit that can't be missed/dodged/blocked (both her w and her ult can both be wasted on minions if used too early, or even in range of a minion) and it takes a semi-skilled player to play her. So, instead of bashing a mid-high skill champion (around a 6/9, in my opinion (no sex joke intended this time)), and saying that (s)he's oh so overpowered, take a minute to think. "Don't blame the support for not keeping you alive, when you dove into the 3v1 under the enemy's turret after the support TOLD you they were recalling, because they were at 5% health"
Oh, also, about her ult. It's an essential survival tool in her kit. It allows her to actually get kills, and to actually get AWAY from losing fights. Removing it would be similar to removing
's Q - it might not be the defining spell in her kit, but it's essential to being able to play her. And compare her ult to lower-cooldown spells with lower mana costs on champions with more mana (cough cough
,
,
,
, and
…) (Yes, I do realize that Diana and Yasuo only do it to enemies they can see. They're still lower-cooldown and take less mana) (you could also make the stretch for
's new W, as, if used right, it can jump her over small walls (about whatever
(another applicable champion) can Q over)). So, again. Stop bashing the champion just because you can't play. There aren't many champions in the game that are unbeatable (even in the right hands. Azir MIGHT be the only one who you could find impossible to kill, between his ult and his W+Q), and not a lot that are even broken (
(in good hands)
, and anybody of their caliber - and even THEY have their weaknesses).
…Do I need to keep going?
