The super itself isn't OP it's the build that you can use that is OP, Hammer of Sol wouldn't be as OP as it is now without their ForgeMaster Perk(Increases amount of hammers and Blast Radius) and Cauterize (Health Back when you get a kill) and the reason you can't 1 shot this super with snipers or GG is probably because of the maxed Armor stat. Just think about there's OP an loadout for each class, the sunsinger has the Tank Build, the Voidwalker has the Nova Bomb Spammer build, The Arc Blade with Razors Edge and hungering blade, The Striker with Unstoppable and Shockwave, the Defender with Armor of light and Bastion, GG itself is OP minus the non health buff and damage drop off without the perk, I have not used NightStalker and StormCaller but I'm pretty sure they have they're OP loadout as well. The last thing I want to say is that if you stay in the same area while my HoS is active you deserved to die by it because I have played with a lobby of highly skilled opponent and they found a way to either evade me or best me when they didn't even have they're own super, you just gotta play smart when you see a HoS. Edit 1: Btw Mtashed just 1 shot a HoS that had full health with a sniper, go to Planet Destinys latest video.
