Malzahar W is luck based.
As a 300 games Malzahar main(I picked him up to counter the unfair assassins last season), ever since he got reworked he became very unstable. All his damage went into his W, which he can not control unless the target has E on it or ulted down. (you lack damage to kill them or gap close to catch them ) Malazahar got nerfed because how noob friendly his kit has become. (you did not need a brain to kill people with W)
W unreliable damage output R damage laughable E damage is at least half of what it used to be (at least feels like it) Q damage nerfed
After the nerfs his current state is useless. His entire kit lacks damage. You full combo someone and ignite them and they still walk away like nothing happaned.
There were arguments that you can reset his E if you use new skills on the target. Well unless the enemy decides to afk in the middle of the lane I doubt you can do this enough time to kill them. Not to mention all his skills are on huge cooldown. The thing is Malzahar does not build CD items. So waiting 20 seconds for a W that ignores your target (you want to 1 vs 1 but voidlings needs them pocket money from minions) most of the time is very frustrating.
His kit is very bad at the moment because his voidlings randomly switch targets if the E expires. In a fight your voidlings (W) focuses minions instead of helping you, because of that his W is unreliable. In his old kit he could command the minion to attack the same target malzahar is attacking with basic attack. Reverting the change to at least be able to control your own skill by using basic attack would solve this critical problem. I know everyone hates malzahar because he can delete assassins, but he is unfun to play with. (reason why I seen noone play him in the past months)
Example how bad Malzahar feels now : You play Annie your biggest damage is Tibbers, but suddenly an update removes the ability to control him, he will attack random targets like scuttle in the river isntead of helping you out when people jump at you.
To me it looks like he could beat low level players, but cant do anything meaningful above plat.
I will probably will get a bunch of downvotes because people dont like him, but that does not change the fact that his kit needs a fix.
