I've only felt like Hammer of Sol was an issue on the small Mercury map with the portal. An opposing team had two or three Sunbreakers and one of them could get around most of the map killing most of our team and generating enough orbs to fuel the other two. I got a few "back in action" pins that round dieing from all the supers. That said I don't blame HoS specifically. Factors like a skill imbalance in teams probably added more to the issue in this case. While I take that match as evidence against HoS I hardly think it's conclusive. The number of matches that a team of Sunbreakers didn't significantly pull ahead is much greater.
