I have been enjoying the new mode tbh, my sniper game definitely improved I think, although it will probably always remain in the top tier garbage, but hey, improvement still! As for the event challenges, I have completed all of them, except the 14 dailies one.
I'm a bit disappointed at the rewards, they're a bit weak, especially if you compare them to the Legendary Hunt event which gave us one legendary character skin (Wraith Night Terror), two legendary weapon skins (R301 Honored Prey & Triple Take Tamed Beast), one epic character skin (Bloodhound Epic Master of the Hunt) and even one rare weapon skin on top of it (G7 Scout Wolfpack). This event is only giving us two weapon skins, 1 rare and 1 epic, all for the G7 Scout that I honestly couldn't care less about (one of my least used gun ever), and that's... it. That's honestly so meager and miserable. I don't care much for the loading screen and loading music, it's nice to have them, I guess, but it's just endless distractions from getting actual proper in-game skins of characters/guns to me. It's slightly better than getting a kill stat tracker though, but not by much.
I bought that Lifeline skin though, cause for a rare skin, it looks dope and it's not expensive at all. We love a goth redhead Lifeline, yes!
