About the hit detection: It has been especially bad today. Tried to play Relic and a lot of the time the Relics I used did no damage despite having splash damage. There's also signs that it's a general issue because I've had the Incinerator Snap melee during the Warlock Song of Flame super also deal no damage at shotgun range multiple times today. It got worse as the day went on though it also seems like matchmaking has also slowed to a crawl. About the unknown buff: For whatever reason on my Warlock, no matter where I am or what subclass, weapons, or armor I have equipped, when I stop sprinting after even just half a second, my Warlock flashes as if he's acquired some sort of buff or some aspect refreshed and the screen also flashes to reflect this. There is no cooldown for this and there is no UI indicators on what exactly is going on. This gets excessive and actually strains my eyes a lot. And it's also very distracting during a gun fight.
