What if, after reaching a certain rank, each faction had a Super that would be available to purchase with Legendary Marks? Each Super wouldn't have its own subclass, but would instead appear as another upgrade column in its corresponding element. My ideas:
[b]Future War Cult[/b]: Axion Storm (Void)
Unleashes four Axion projectiles that seek enemies (faster than Axion Bolt) and explode
Modifier 1: Add an additional two projectiles to the storm
Mod 2: Each projectile moves faster and seeks enemies more efficiently
Mod 3: If an enemy is hit by a projectile, every subsequent projectile will deal additional damage
[b]Dead Orbit[/b]: Skyhammer (Arc)
Summons a massive bolt of concentrated lightning from the sky
Mod 1: Staggers and damages nearby enemies
Mod 2: Skyhammer blinds the it's target and causes damage over time
Mod 3: If the target enemy is killed, Skyhammer has a chance to link to another nearby enemy
[b]New Monarchy[/b]: Blazing Armor (Solar)
Surrounds you in light that offers greatly increased protection against all types of damage (cannot sprint when active)
Mod 1: Melee attacks deal much more damage while Blazing Armor is active
Mod 2: Nearby enemies will take Solar damage over time
Mod 3: Enemy projectiles have a chance to bounce off completely, dealing no damage to you (doesn't work with Supers, Rocket Launchers, or Shotguns)
Post your thoughts below, as well as any suggestions or ideas of your own.
