Nothing needs to be done. People need to adjust to the meta. Sunbreaker makes a bad player average, an average player good, and a good player great. For the first time we have a geat PVP subclass that's a range build. Sunbreakers are not overpowered players need to adapt to the strat to stop them. What Bungie needs to do is replace that extended melee from the Warlock stormcall tree. To me that's a bigger issue.
