SO then Freya tactics:
Freya Phase 1
Your main tank should pull Freya and tank her roughkly near a tree but mostly in land.
This gives room for the adds to be tanked and dpsed near the river bank.
Phase 1 Adds
Freya cant be hurt so no point in dpsing her at all in phase 1, unless achievement but anyway.
There are 3 groups of adds:
Single Big tree
This guy needs to be tanked right near the river bank, or where ever the raid decide. With it beign tanked near the river, there is no range issues because everyone has a good idea of the landscape, river is more icopnic rather than a tree ... which tree? etc
Only thing to remember is the OT has to be ready to pick up the next wave of adds so that things run smoothly.
The dps should mainly focus standing under a mushroom near the river bed, again this leaves a nice space between freya and her add, which makes it easier to see things.
Little fucking flowers
One member of the raid, will put a symbol above themselves this makes it pretty easy for everyone, yes everyoneto bunch under them for aoe.
Aoe needs to be controlled and constant till 30% health, this way the main tank can, after a while, move away with his dedicated healer from the stack of people.
If they away from the fight we cold ahev a random flower missing dps. Which makes things longer.
After 30% everyone needs to either do 2 things:
let a mage frost nova, all melee move away and everyone continues ranged aoe.
I dislike this tactic because depending on raid set up you cant awlays do it, people dont react all the same, some are slow i mean.
Easier way to kill the flowers is to all stand still. Change from aoe to single target dps. If you run away to get range, means larger space for heales to cover, moe flowers run further away.
Triple goodness of adds
These guys are a pain in the ass.
To explain the different adds might help.
The storm lasher will basically be a moving aoe, all melee under its storm take aoe dmg, surprising eh.
It isnt a lot of dmg, can be healed through and the storm lasher is quite a slow mob.
The Water elemental (as I call it) can be tanked. So if the OT faces it away from the rest of the raid. It will only charge him, if he can taunt it just before it throws him, it will run traight for him and then follow him back to wherever he was or a warrior or feral druid can just charge him after knock back. Trick with the water elementa is to burn him to 30% quickly so the OT can not worry about other people in his line of sight.
Lastly the Snap lasher who has been kited by a dps that does instant spells/abilites, because the snap lasher needs to get its debuff stacked to 20 quickly so it becomes immbile, and when the dps go to dps it, a mage or priest can dispell its buff so its not so lethal.
Then everyone must bring all the adds together.
Most of the the storm lasher will follow the raid anyway, so the OT just needs to bring the water elemental to the other lashers.
Phase 2 Freya
Phase 2 is very simple. Tank kites her around the room whilst missing the glowing green patches on the grass which are bombs.
So if you stand near 5 of them your dead, but only 1 or 2 is easy to heal thorugh.
Constant dps and BLoodlust is all that is needed to down Freya from here.
If u see a frozen/rooted blahblah herb pack RUN! coz there may be aoe incomming
