I really like all of these ideas. They're all simple and easy to understand, and can go together well with other Exotic Armor pieces. The Quiet Before would really give a reason to use Storm Grenades over Pulse Grenades, and, combined with Crown of Tempests, can be very nice for wiping out mobs of enemies with a single Grenade. Plus, Crown of Tempests would give you that Storm Grenade back faster. Flying Squirrel gives me the feeling that it's much like Icarus Dash for Dawnblade, and Twilight Garrison for Titans in D1. Though, this could actually combine well with The Dragon's Shadow for swift counter-attacks and nimble handling. Honored Indefinite doesn't really have any Exotic that combines well with it since none directly affect a Titan's Fists of Havoc, but the concept is simple, and I know I've killed several Titans mid-smash before the boom landed. It'd be a pretty scary thing, to discover that he moves with a mightier force of gravity! Simple, but effective. And these are Class Items, so if I recall from D1, they can be combined with other Exotics. Still, simplicity is sometimes the best.
