That is an example of the " hit and run " tactics that werewolves do best, for the most part you want to try your best to ambush your prey and surprise them with a power attack. By spamming the power swipe/attack you ensure that your target is on his/her back once they are on their back you are in turn able to control the fight and thus will walk away with little to no damage to yourself. As a werewolf it is important that you take control of the situation as soon as possible, the best way to do so is to use my " herding " method or to spam the power attack.
Mastering the sprinting power attack is another must for werewolves, once you have gotten use to how your beast form reacts when sprinting you can make very sharp turns while sprinting. But it doesn't come over night, you will have to practice this in order to be able to combine the sprinting sharp turns with the sprinting power attack. But once you have mastered it it becomes your most powerful tactic, a sprinting power attack has the ability to down just about any NPC in one pass. A fully perked werewolf can and will kill a giant in one pass, a mammoth in two to three. So it is pretty important that you learn how to attack while on the run, not only will it dispatch your prey in a hurry but it will as well create openings for you to escape if and when you land yourself in trouble.
On the subject of a fully perked werewolf....
It's best to focus on the first perk, the " Bestial strength " perk. Once it's filled out your werewolf will have a damage output of 160, which is more then enough to survive on master difficulty. So you should focus on that perk the most so that you can put your prey down in a hurry. At the same time ( or after ) you want to focus on the right side of the Lycan perk tree, the side that has the Animal vigor, Gorging and Savage feeding perks. The goal is to reach the Savage feeding perk as soon as you can. Once you have gotten the Savage feeding perk the rest of the tree will follow with little effort. It won't take long and everything gained is pure gravy!
There's much,much more that aids your werewolf. There's quite a few normal perks that carry over into your beast form aiding him/her to become a very powerful werewolf. There's also spells, and potions that carry over along with certain standing stones. I will out line those as the questions come in, it's quite the list so I felt that it would end up being too much to read thus killing the topic, so I will answer those questions as they come up.
( Once again I apologize for the read, which is why I left out a good bit of information to save you the reader from a wall of text. I will answer any questions that are brought up.

This is a topic for werewolves to share knowledge and stories of the hunt, to show that the beast form is truly a force to be reckoned with.

****WARNING****
To any werewolf hunter/flamer who dares to nose around this topic......
You are entering the den of a very old and very wise werewolf who doesn't have the patients to deal with you. You will be dismembered and devoured in the most painful way. So consider this your friendly warning, to not poke your nose in where it doesn't belong. If you choose to not heed my warning then....
