Playing this setup I got to 2.3k rating on arena tournament. This setup is pretty easy against several combos and in the same time almost impossible to win against others.
VS Disc Priest + Rogue
Basically there are two hard phases in this fight: good opening and dealing with kiting and drinking.
Start and opening
Shaman puts earth shield on himself because most likely they will go for shaman, and feral should survive the burst while shaman is sapped. Totems should be set behind pillar or under the bridge.Poison cleaning totem, tremor, nature resistance(rogue’s poisons do nature damage), and grounding.
After initial positions are taken there are two variants for feral druid:
1) Wait for rogue to open, and stun him giving your shaman time to move away. (At lower ratings you can just open rogue and kill him by CCing the priest)
During the whole battle it’s important peel rogue from shaman. If you let the rogue to sit on shaman, you are in a very high risk of eating many double fears with resaps. Peeling could be achieved by cycloning, stunning and charging(makes him stand at one place for 3sec) the rogue. While rogue is CC’ed shaman must move in wolf form no matter how low his HP is. Just run away, make sure that rogue is far and than heal up.
2) Second option is to open the priest asap. If rogue managed to sap shaman you can cyclone the priest, switch to bear form, try to roar to find rogue in other words kite and survive until your shaman heals you up, charge\stun priest to stop him from moving closer to shaman and fear.
If after you open the priest they still decide to go for shaman, feral can pop berserk and make some pressure on the priest to not let him burn / dps. If priest is dwarf I always go for rogue at start(Dwarf’s racial ability removes all bleeds and literally fucks up feral damage and burst).
The battle
So after you survived their burst you have 60-70% of victory if you don’t make mistakes with fears and resap. Which is not that easy, because as soon as rogue wastes some cooldowns and priest will get low on mana they will kite as hell, playing very defensive and annoying.
The goal is to kill priest controlling the rogue and not letting them reset.
On low ratings it’s usually easy to kite priest’s fiend and win on mana. Feral must make sure his innervate will not be dispelled by priest.
