I have major problems playing versus Berzerkers, so naturally I came here for guidelines. "Git gud" was the top answer (thanks everyone!)
Use feints more, this will really annoy people especially when used in the "infinty and beyond" -chain he has. Beware of the leap heavy, it's easy to parry/counter.
Also, try to get as close as possible w/ your axe wielding midget to get the most use of him
My recommendation would be to instead look at all the previous posts made by fellow players asking the exact same thing. There has been more than enough responses to start your research there. The community has done well to answer any questions you might have AND there are reddit posts/ youtube videos and even streams that show you. Soooooo please check before you spawn a copy thread (though I am sure you meant well so no worries)

Then watch Youtubes. This guy plays to win, and plays the core elements of the game. Watch how he uses Berserker.

Or watch any old vid for ideas

One thing I'll add is that I feel you can be block heavy, or dash/deflect heavy, and if you're real pro mix up between the two. From your defensive foundation you can build your offensive approach from there.
