I won't ever defend any Global/Steam imbalances in and of themselves, *but* I understand Hunters are extremely easy to break so they likely overdid it in the opposite direction. Case in point, by memory, an endgame Evoker was massively better than a comparably endgame MM.
Curiously, which might help here, they did buff Strikes to be affected by guns. If you look through guides of the time, the two best choices for Strike sets were Bolters (for slots) and Cannonades (for damage and interrupt). So if you could get a good set enchanted to, say +7, you'd likely have a far easier time.
(I understand that being boxed into Strike builds with specific guns is not great or really logical - ideally it should be mods to the kits and guns that fix such imbalances. But in the meantime, this could offer *some* direction.)
