Just reduce the armor resistance a little bit so it can be killed by GG and high impact snipers, it'll give other supers a chance of killing one as well, they'll keep tier damage and the 7 hammers and such. You'll still be tanky. Running from them should not be the best strategy for engaging Hammer of sol.
Edit: yes it is possible to Oneshot a Hammer of sol with a GG and a sniper but that's if they don't have max armor, if a Titan runs max armor it can love those attacks, that is not okay. Just like how if a sunsinger wearing ram with an over shield could live a GG shot. So just slightly reduce the damage resistance, you'll still be tanky as hell but you can still easily die from skilled snipers and other supers.
EDIT: when I say slight damage resistance reduction I'm talking about a 5% decrease.
Anyone else finding it funny about people bitching that they couldnt one shot a sun breaker with a sniper? Most of you fools cant one shot a regular guardian and have to take 2-3 to get a kill. So why not take a second shot on the Sunbreaker?
