Hello a zilean supp here
I am a bronze player an just so you know i just play for the fun of the game. i main supp and i have done that for a year and a half (i know that he is not the best supp but i like him and he is the best i can play) and every time i pick him i get a lot of hate just because he is not one of the best champs out there but i always ask if they know what my ult do(i know a lot of new players who dont know.) and i always tell my team mate to just do there best and that its a team game(i hate when they complain about being killed by 2 - 4 champs) and what do i get for it a lot of hate and degrading comments but i just take it with stride and that its a team game and that as long as the enemy is dead then it do not matters who get what kill. Why do people hate zilean 

so much i mean if you can play him right then he is a beast well thanks for reading this and pls tell me of your own stories about your favorite champs that get a lot for hate:) pls no flames or toxic comments :)
"People fear what they cannot understand."
for the mana save and
as supp item and the rest is mostly base on how we are doing. if we are doing good then i go a lot of ap just so i can help and if we are losing then i go tank so my build is based on how well we are doing but thanks for you advice becaus unlike a lot of bronze players i know that im not the best player out there and if i do a mistake then i dont blame it on anyone else :)
and I build support, no AP.
