3.21 Explosive arrow ballista elementalist - good dps, decent speed & survivability

pob: https://pobb.in/PT757UAj8wrs

28m dps against uber pinnacles and 15% cull ~50k armour w/o flasks 150ms w/o phase run

It's hard to find an good all-round ele ignite build now within a decent budget. The biggest issu is that after molten shell being nerfed, stacking armour and using molten shell requires too big investments. And elementalists don't really have many survivability options when not using a shield.

Good thing with EA ballista is that this is not a top-half talent tree build. We can reach iron reflex (determination & grace, 50k armour w/o flasks and a full molten shell), we can cap spell suppression, we can have high ms speed, while still having enough dps to skip uber SE phase. And there is enough space for doppelganger and divine flesh (cloak of flame and 4th vow are also good options)

The build is designed for totem playstyle so though it has a good max hit (considering it's SC elementalist and no mb), its ehp and recovery is not very good.
