fed? the build I'm proposing is really cheap, like reaaaally cheap. Lich bane and RoA are only 300 gold more expensive than a frozen heart (that is around 4 assists). You are just insulting me personally without giving any valid reasons. Really.... blitz has a 1:1 scaling ratio and you want to rely on bases when he can have 2 items that synergize extremely well with him and can potentially enable him to dish around 3000 magic damage in the spawn of 7 seconds AS A SUPPORT. He would have resistances and value from his support items (pretty much all give CDR and lich bane gives 10%) while scaling and doing a ton of damage.
you have to play blitz who is mostly close ranged damage
You do know he has his Q to pull target, and his E on a 3 second CD while having his W and Righteous glory to chase and slow right? You are clueless, and I never said this build would solo carry challenger games, but it really gives you a ton of damage given outside of transformation champs and a few exceptions like lux, kass, kog and karma almost no character can optimise Ultimore as much as blitz can
