Blessed or Survivor Insignia on Ele

From PvP perspective (excluding AB, CMs, Codex) which is better for each arena (RA, HA, GvG)?

Personally, I normally take Blessed in HA and GvG while taking Survivor in RA. However, for a SH ele I've heard that Survivor>Blessed for that build.

Thanks

generally boils down to if you are running aura of restoration or not

blessed if u got 2 enchantments

if you are running with two elements you should use prismatic otherwise blessed.

This is true.

Or Master of Magic as your elite

If you're not running Aura Resto, go with Survivor's or Stalwart.
