I just want to be a wizard who self-casts fireball as GGG intended it...

As the title states. I've always had a thing for fireball and have wanted to make it work as self-cast. It's definitely not meta but I still gave it a shot. There isn't much currency put into this build and definitely room for improvement. I die ALOT. Like at least once or twice a map.

I understand why I die. Mainly I'm not not running grace or determination even though I spec'ed into grace reservation on the tree. I don't have enough reserved mana so I could either save for enlighten 4 or drop a damage aura. And ultimately I don't have capped spell suppression (77%) The intent of the character is to be a mapper, but I was also hoping to be able to boss by going elemantilist and focusing on the ignite.

My thoughts to fix the build are dropping "The Gull" even though I REALLY like it. Spell suppression/reservation helm. Drop a damage aura and fit grace into the build. I can run dual circle of anguish, or polaric, or keep snakepit. What gem links are optimal? Maybe elemantlist isn't the best way to self-cast fireball. It's very overwhelming. Also I really really am not looking for an omni or ashes build. Looking for advice. Self casts fireball builds don't exist and I think i'm beginning to know why. Also I'm sure my gem links are pure trash. Any help would be appreciated.
