Either nerf armor from 55 to 50 (same as BD) or overhaul the class, making more perks useful outside of Hammer of Sol, in exchange for some power taken off the super. But honestly I think the only problem is the Solar Armor perk on armor. That's the thing that stops GG one shotting and only leaving the Titan with a minicscule amount of health. Without Solar Armor it one shots HoS. Maybe make it so Solar Armor perk disables when in super or something, only active outside of supers?
