If anything, this update has made me try Striker more. I was a Sunbreaker main with Suncharge and Cauterize but with shotguns being less around and shoulder charge damage increased, running Striker has been fun. Aftershocks has been doing great for me for lightning grenades too.
I just use sunspots and fire keeper half the time or I'll just use forgemaster with cauterize maximizing the number of hammers I can throw. I tend to get 3-5 kills with my hammers every super while using it. I personally don't like striker anymore because the last 3 perks on the skill tree are so abysmal. Unstoppable doesn't even work as a perk, shoulder charge is still too slow and there is no incentive to use juggernaut because of the nerf as well with the nerf on shotguns. But if your doing great with striker then that's more power to you my friend
I mained Striker before Taken King, but went to Sunbreaker ever since it's released. Haven't touched Striker since, even during the Jug/shotty days. Just somewhat fresh now. Feels more confident to use Shoulder Charge. Yeah, not as awesome as it was back in the day, but I used it for movement more than offense back then anyway
