Only two sniper arc types can one headshot a gunslinger, bladedancer or sunsinger during their super: mid-high and high impact snipers. So just there you have to disqualify more than half of the snipers that fit into the lowest, low and mid impact (planet destiny did an article about this a while back). Titans are meant to have more armour hence is only logic that you need high impact snipers to one headshot. Heck Sunsingers with radiant skin can survive mid-high impact snipers why won't a fully armored Titan?? Black Spindle won't be the only option for this (Y2 Efrideet's Spear??)... You can talk about HoS being op on a number of diff things such as the hammer splash damage size, tracking hammers, cauterize... but the one sniper headshot argument is just completely flawed...
