I think the main problem is nothing to do with ele, it's to do with how we play classes. We only use glass cannons or full healers/buffers.
Ele is all of them, filling multiple roles so something like celestial gear would make them more tanky but also reducing there dps. Since everyone cares about the numbers and buff uptimes no one would run celestial in a fractal or raid. It is probably only used in wvw.
I don't like the meta at all for pve and would rather see people contribute there individual classes unique aspect to a group, rather than damage number.
