40+ Games with new Akali

So ive been an Akali main for almost 3 or more years (platinum 3 currently) and I feel about the new rework is that she is useless. She doesn't feel like an assassin, (with over 50 games, including normals). In her learning phase she feels pretty good, nice amount of poke, not many counters since her w gives true invisibilty, but the energy cost is so high its just useless in team fights. You can hit a q couple of times and that's it, if you couldn't kill anyone cause of the cc or tankyness you just die there. Her r is good in some situations but the hard cc of many supports or shields makes you useless unable to oneshot meanwhile zed, fizz, etc. easly come, kill, leave while with akali you might get a kill on the adc (example) but now your screwed because if your team cant help you, you die. In many games ive played if my team is far behind we cant comeback, and i feel kinda guilty cause even if i farm, ward, objectives... at the end we lose cause of the useless my dmg is. Her passive feels pretty weak too, in lane its great and all, but as i said, in teamfights her passive is useless cause of the ap scaling. With atleast 2 items of mr i feel completly useless, tank, mid or adc, i just feel like i dont do dmg even if i build penetration. Overall i have 64% winrate out of 44 games and i mainly play her top cause of her nice poke which made me climb easly thanks to shutting down the enemy laner. Even after being fed, for exaple, 5-0 by the enemy laner i feel i still cant one shot until 40 minutes in, with full build, which in many games wont get to that minute mark. Honestly i feel like im being carried when i play in many games with her instead of being usefull. Thats my opinion, feel free to disagree or agree, comment or not... but i would like an solution to this cause i know she wont be in the competitive scene for now. http://euw.op.gg/summoner/userName=Akali%20Demon
