Knucklehead Radar is flat out not very good. When comparing it to other exotics it just doesn't stack up. As such seeing someone actually using it is exceptionally rare to the point many players probably forgot they had one. It essentially just gives your primary weapon Third Eye. As far as exotics went in Vanilla that was pretty ok. Even then it was still probably the weakest Hunter exotic, but its competition wasn't a great deal better. Now four expansions later power creep has set in and Knucklehead Radar has been left in the dust. Other year 1 exotics like No Backup Plan, Apotheosis Veil, and ATS/8 ARACHNID which were also pretty weak were given new and extra abilities on top of their existing ones to make them more attractive when they were reintroduced in year 2. Poor Knucklehead Radar wasn't looked at however. It also deserves an upgrade to keep it desirable with this current supersaturation of exotics. The helmet being rendered completely useless just by actually having Third Eye on your weapon means it needs to widen its effectiveness. I have two suggestions on possible ways to improve it. - Allow it to grant Third Eye to all your weapons (yes including snipers) instead of [i]just[/i] your Primary. or - In addition to granting your Primary weapon Third Eye also give your Primary weapon Relentless Tracker. The former suggestion would probably have a much larger impact on overall gameplay than the latter, but I don't think either of them are too extreme and keep with the spirit of the exotic. If you disagree i'd like to hear what you would suggest to make Knucklehead Radar competitive with other exotics. This is really just hypothetical well-wishing anyway so it makes for good discussion.
