i have both sets and i wanted to know if i use vyr, my archon will proc all the damage types? and trigger all meteors from tal rasha? or just the element i have more %?
Archon will only be 1 element, but you can have a Familiar, an armor spell, a Follower and some items that deal damage on their own. Not sure about Magic Weapon runes. I suppose they also proc Meteors.
Magic Weapon runes do proc meteors as long as they deal damage somehow (i.e: electrify, ignite. As far as i know conduit, force weapon, and deflection do not proc arcane because they technically don't deal any damage. I've tested some and didn't see arcane proc from those runes but it could be a really low coefficient.) The weapons elemental damage property will proc as well, so specced properly with the corresponding familiar element you could have all 4 meteors proc. eg, Gesture of Orpheus proccing arcane with the ignite rune to proc fire, using electrocute to proc lightning and the ice familiar to proc cold. Though it isn't worth gimping yourself to get all 4, 3 is enough. Keep in mind though with this scenario if your archon isn't lightning you will lose the lightning meteor once going archon since you will no longer be casting electrocute.

Keep in mind, that I have a TF to proc the lightning meteors.
Edit: Magic Weapon works, so you could use Electrify to proc the lightning meteors.
