Heimer's destiny
I'm a Heimer main in the past with over 800 ranked games with him. I stopped play Heimer in S5 because there was so much stuff to counter him. This season Heimer is just an empty space: extra buffed malmortius makes hexdrinker ever more popular (and this is the best item to counter Heimer). Added Steraks - another great item with shield to counter Heimer.
Previous season Juggernauts became true terror for Heimer - fat, has lot of utility to reach dinger and tons of damage to kill him. They made him unavailable on toplane. This season Riot gave ludens to junglers, cannon range to adcs, made jhin who can kill Heimer's turrets from another galaxy.
Next patch we will get new mages - Zyra with uber huge Q which can clear entire lane out of Heimer's turrets. Same time she can summon thousands of plant which will distract Heimer's turrets attention.
Velkoz, who always was beating Heimer in late, will become even stronger: no Q indicator, and true damage on ult.
Zhonia nerfs - item that Heimer always gets. This is just a straight nerf to our hairy friend.
And nothing to compensate that! I remember how Riots said about dreams to see Heimer as popular pick on proscene. I guess it's time to do something for that.
