You serious? You obviously have to idea what a true Berserker is. Let me school you with some off topic stuff babe.
As a Legendary Astaroth player, I recommend you as an apprentice of Astaroth to get the feel for all of Astaroth's moves. However, as a shortcut to being sufficiently better, you should rely on his alterantive grapples (The one where you swing the analog stick) & his low grabs. Bull rushes are only a continuation of putting supreme pressure against foes, however, don't use them too often or else you'll end up blocking & playing the guessing game where the advantage is on their favor. Mix it up with

Bull Rushes are unique when you know your about to be blocking again. When you know its your enemies turn to strike, start using some meter on those Bullrushes. It'll help get some of that pressure off you while you strike through. If you happen to succeed with the second hit only, quickly use your d-pads to move sideways & press

. If he's near a wall, use some meter on that side step move. Then grab his ass to annihilate him with

What Astaroth provides that not many characters do is bigger reactions on impact. Take advantage over that & use those heavier impact moves to allow you to keep striking continuously with various moves. Even a small impact can lead up to a big one for continous attacks if that smaller impact is a successful hit. Become proficient at that & then you'll soon know that you control meter breaks. Also, you gain more confidence to dealing with pressure. Blocking should be the least of your worries when you have this down.
Lastly you should have some focus on is Astaroths Range. Astaroth is (in my opinion) the best area controller of the battlefield. When you know your enemy is at a great distance, rely on his

. The purpose of those moves will decide its own advantage. That will either be more meter breaking damage or successful Hp damage, with continuous long range attacks that will eventually get you close enough to continue the heavy impacts. DO NOT be reckless with these attacks, because if you failed to lead your shot correctly, you will pay a price. Don't let that get you down though, once your proficiency rises up, you'll learn that you won't fail 98% of the time.
As for the start of battle, I like to use my long range attacks on opponets I know who back up in the beginning of a fight online. As for cpu's & online opponets who don't back up, I like to use


or


for a really good start. If you feel as if you need to back up first, I would use either my long range attacks or my previous start ups that I displayed.
In the middle of a fight, I sometimes switch it up with Astaroth's other bigger reaction attacks. The ones that make you hold your gut or spin you like a ballerina or fly like a threw up baseball for me to smack. These attacks I'd like to recommend to enemy side steppers.

Astaroth's combos; the only combo you really need to rely on is his wall death combo. Mainly you should focus on controlling meter break attacks & area control attacks with a mix of grapples. If I were you, I'd start raising my proficiency with those methods. Gaining proficiency to rise yourself to the next level in using Astaroth can be raised in two ways. One fast way & one slow way, you don't have a choice but to accept the one thats given to you.
Exp for Proficiency Level-ups
1) Win battles (Slow way)
2) Lose battles (Fast way)
Advice: Don't worry about the whinning complainers who would bitch at you because of too much grappling. Astaroth is meant to be a grappler due to his air grab, alternative grabs, low grabs, lye down grabs, weapon grabs, & flame grabs.
