Based on KR, they are buffing the range on flame buster as it most likely was an unintended nerf - the damage of q buffed flamebuster was untouched (and most likely what you are seeing in these cherry picked clips.) It just shows that instead of proper balance the devs just randomly nerf and buff skills, which I am sure all classes are familiar with. Giant leap has always been strong and with enough ap will do a lot of damage. If I am not mistaken most ults do a lot of damage with tons of gear. The giants in these clips are also abusing click to move in order for the ult to focus much more damage in a small area. This type of clip is not new though, and does not only apply to berserkers. I am not really trying to justify if any class is op. Personally my belief is that the FB nerf is not a bad thing, but changing the pve damage and requiring different key inputs for a pvp cc removal is a bit frustrating. These changes to berserker are making the class more clunky and introducing bugs every week with no clear resolution, mostly via hidden changes or vague patch note descriptions. That is the main issue that I have at the moment, and is not unique to our class. It is something that any player should be upset about - we just vent in our own class forums because it is what we enjoy playing the most.
