as posted yesterday wanted to do another build.....

so i went to tft and searched for a premade elementalist ea ballista build for my budget,

any ideas how to improve this?

pob is this https://pastebin.com/QiDTYiX7

damage is good, dies on occasion no idea why yet, did maven last night, died during last memory game.....thats it....but asking for input, coz i noticed that the watchers eye needed an upgrade, maybe u guys have other ideas, since the attack speed is still a bit low, and the skill links seems to be a little scattered....
