No one's been bullied here.
This build is just wrong and it's not about the skillset but also items choice.
Like you don't need mara, what you need is atma's and 3 summon amulets for precasting.
You also don't want to use normal attack arrow with zero attack rating but instead like explosive arrow, but it's your build after all...
Witchwild String has Lv20 Magic Arrow, so it's not only a good Attack Bonus but it's bypassing some PI, and inflicts Amplify Damage. I don't need Atma's when the bow is already applying AD.
Now, if I switch to a Faith runeword for the aura, then Atma's Scarab becomes the play.
