The biggest buff to Rage/Focus was the nerf to Stun Bubbles. The biggest nerf to Rage/Focus was the buff to snipers. The intrinsic changes to Rage/Focus were minimal. In the immediate run, Rage/Focus should have a field day as the availability of good snipers is extremely limited.
Stun bubbles going is a good thing. Regarding rage maras and snipers. IMO, a smashers job is not to chase down single targets. The spec shines and is more useful in staying in the mid of a group and damaging. If you want single target damage carnage and anni are much better. Also snipers are a threat to everyone in the field, but it's not a smshers role to take them out, this is better left for a shadow, operative, sage, sniper or commando.
