Aegis > RUN

[Zagen]

Magical Damage is Rune Fencer's calling card.

So where are all the single element magical damage dealing no/minimal melee damage dealing mobs that would allow it to shine above even Aegis as the superior magical tank?

You could argue well the AF/Relic/Emp/Mythic/Merits are all missing but all of that will have to address the fact that when something casts multiple elemental damage types and deals high physical damage RUN's capabilities go to the OP's point of Aegis > RUN.
