Everyone always play kat with too much early damge...lets think about a little more defensive items...If you take mid you will be against a mana champ in 90% of games (Others Like Morde kat akali) If you dont go too offensive they will be so greedy to kill you & thats the piont they will spent all of their mana to make dmg to you but your health will regen in a few mins you just need to use your W to make more dmg on Q & use it on a minion.
You will see that you Always have more Hp than your oppenment...Its not easy to kill him without your Ult but you can gank other lanes & take some dmg.
You will see your diffrence in the mid game & late game.
YOU NEVER DIE!
Take Exhaust & Ghost ... To make safe yourself. You will see the power of ghost in the teamfight.
For Example I have a record from one of my games...its with 200 ping...
