Beyond 3.0 Primals, their weapons and the elemental wheel
With the inclusion of Shiva to the game, the Primals now complete the elemental wheel reminiscent of past final fantasy games.
The following suggestion will look at a way to incorporate that wheel as a tactical aspect to Primal fights in the future - assuming that there will be a Savage mode Primal encounter added at some point down the line. This suggestion isn't a hot-fix and would require time to balance with current/upcoming gear.
(At present Extreme encounters are challenging enough, hence why this is titled a Post-3.0 suggestion).
Ok, this is going to be a long read, so first off some reference.
The Elemental Wheel:
Earth > Lightning > Water > Fire > Ice > Wind > Earth
