Finally seeing Hawkmoon drop from a heroic Undying Mind strike 11 days before House of Wolves. Had it levelled the same day (this was before motes could be used to level, so took a lot of xp). Getting Vex from my first (and only) level 30 VoG (with 2 helms). I think I still have the screenshot my PS4 took when the trophy popped somewhere. Watching a hunter blink straight downwards jumping over a gap in the broken stairs on Sector 618 during IB Rift. It still makes me laugh. Getting snipped in trials whilst throwing a glacier grenade only to have the opposing hunter shatterdive into it killing themselves and their teammate (on titan at the time).
