People have become so scared of their channels getting shut down for not having enough original content on them that they just load them up with constant garbage editing so that it passes as "original content" and won't be penalized. They don't realize that they're slowly killing their channel. 142K subs, 3K views, 124 likes are TRASH numbers, especially when you're one of the few Hearthstone clip channels left. Channel owner doesn't give a shit though. They adopted this new approach months ago and people have complained about the overdone editing on every video since, and they just keep cranking them out because making pennies on the dollar for shotgunning memes and loud noises takes way less effort than actually trying.
Blame the garbage RU-vid policies regarding copyright and demonetization. But I agree some effects are just grating in how often they are repeated, the whole "Wombo Combo" sound clip in particular.
