Crest doesn't provide any sort of class bonus. In certain situations dieing repeatedly does add more time to the revive timer. Immolation Fists were bugged. Explosive Pyre would not trigger. Not sure if they are still bugged. Tracking on hammers is and has always been useless. I already think that using Landfall should take some of the super. Getting an extra Golden Gun shot is making the easiest to use most lethal super even more so. Why would you expect to get that for free? Aside from Impossible Machines none of the exotics you mentioned gave an extra charge or use to a super.
