I will list the mandatory things you have to do to be a descent barb :
1) get IP on ALL your team, from 0 to 15 mins ( discussed later on, sometimes u can skip IP).
2)Get 5 globes for your WD. it will make him tankier and increase his dps. it's very important that when u start to pack mobs, you need to spam ground stomp to generate globes ( and for that, the more mobs the more chances to get globes).
3)spam the war cry when you move, to increase movement speed for your party( especially the WD).
4)refresh falter all the time, but especially when the WD is gonna burst/ necro is gonna burst.
What you need to do to be a GOOD BARB :
1) Lag management : if your team dies because of the lag, you are probably responsible for that ( hello HC players).
The lag will depend on the mob type, and on the density. needless to say that over 8/9%, u need to take care and anticipe the lag. IF ITS GOING TO BE LAGGY, REMOVE SOME MOBS with rageflip, dont let your party die.
NB : I'm used to play with all top players in EUROPE, only one other barb is doing it, (>3 Nyuuk) . #hopeotherswillreadit.
2) SHIELD PYLON : this pylon may kill you (#lag), or make you loose a lot of time. I wouldn'( recommand it to take it over 7% progress around you. it's ofc situationnal, but it's ALWAYS better to take it after the WD burst.
3) Getting elites in the middle of the pack : YES, you took rageflip. if you wanna use it properly, be between the elite/mob you want to pull and the pack, and BADABOOM SURPRISE, the elite will be in the middle of the pack.
Why is it that important? because the better the elite is surrounded by mobs, the more he will suffer from area dmg.
4) PYLON MANAGEMENT : tricky part of the game. You are supposed to have a pylon every 25-30% progress and 3 to 4 pylons in the GR. this is very important that you check the progress for that.
How to become a GOD BARB?
1)Burn Pylon spots when needed : if you don't want a pylon at a precise position and you are about to make 10% ish progress, hence making the next pylon appears, just burn the pylon, aka, go on the location spot to discover it and avoid having one.
YOU NEED TO KNOW THE PYLON SPOTS AND CHECK YOUR PROGRESS BAR AT ALL TIME.
2) COMMUNICATION : this is KEY : u have to know
- when the WD wil burst, or let him know to wait because you are about to bring more mobs/elites.
-when the Necro CD burst is up.
-what are the elite life %, to know if u have to move to the next point or not.
-is IP NEEDED? ask your team mate, depending on the danger, u could spend more time bringing mobs and not come back for a not needed IP.
3) you DONT NEED TO PULL ALL THE TIME, sometimes it's better to leurre your enemy. What I want to explain is that sometimes it's better to walk around a bit next to the elite to make him follow you/get out of tricky spot. if you use rageflip it will only slow him or make him stay at the exact same position. this is very situationnal, but if you wanna be a GOD barb, you need to manage that
I will update this build if I have other points coming into my mind.
if you have any question, do not hesitate to jump in : twitch/hoxango
PS : the video is a footage taken from stream, I'm usually playing barb everyday so I might have other videos coming, especially during push But the gameplay is the same from 95 to 130+.
