Question about Heimerdinger build
People on the game are rude, that usually doesn't get to me, but today someone criticized my Heimerdinger build which got me pretty upset. But then I have to wonder if the guy was right, and maybe I'm not playing right (as if there's only one way to play). So I'm curious what you guys think. I'm sorry if this isn't in the correct board, and I'm really sorry if this is breaking board etiquette, I was just curious about this and couldn't think of a better way to get an answer.
I started out with Rylai's Crystal Scepter because I was laning against LeBlanc and I needed ap and health so she wouldn't jump in and kill me so quickly.
Then I got Morellonomicon for ap and mana regen.
I died a few times because I was really squishy -and I'm admittedly not that great of a player- so I decided to get the Guardian Angel. I thought I needed to boost my armor and magic resist and I thought that if I died under Heim's turrets, it would act almost like Zhonya's Hourglass, giving my turrets time to damage my opponents while the effect was taking place. Is that a reasonable assessment?
Next I got Zhonya's hourglass for the ap and armor. I was building up for a Rabadon's Deathcap, but we won before I could complete the build.
The guy who criticized my build rudely asserted that I should get Morellonomicon first and then Zhonya's, and that if I build any other way that I'm building wrong. Also he claimed that getting Guardian's Angel was a waste of time and a poor build choice. He told me I should max ap and worry about nothing else. Is he right? I understand that I should try and max ap, but I should invest in a defensive item like Guardian's Angel if I'm losing, right? Idk. Any input here is greatly appreciated. Thanks forum.
