PoE Thebigfreeman builds

new player here - lvl 94 Wave of Conviction elementalist in standard league. Following build from POE Vault. I can run T16 but most rare map mods are a no-go for me - I started some of the elder/shaper quests but that's it. I know life is lacking. I'm not sure adding 500 life will enable me to really step beyond my current plateau, but you guys know better. Please be nice with your comments! The POE reddit has been rude to me when i shared my build before 'this sucks' and 'omg this is so bad' does not really help new players.
