From LFR tactics
Positioning
During phase one, ranged stack at the edge of the pool while melee stack behind the boss in the middle of the room. Face the boss toward ranged until the first Void spawns, then flip him to face the back of the room. In phase two, the raid simply stacks on the boss to ease healing.
From Icy veins Tactics
The idea is to have the Ranged group stack about 20 yards from the boss and the Melee group (tank included) run to the boss. The exact positioning of the Melee group does not really matter at this stage, only that the tank must make the boss face slightly away from the ranged group.
Not sure if the edge of the pool to the centre is 20 yrds ( I think it wouls be more) but we could try both of these out and see, just to verify a good distance. I like the little diagram the Icy Veins tactic has to explain positioning for the pull and up to the summoning of the ball. -
Wich would then change to this when we start the series of bounces. -
So other than being unsure of distances and if the ball isnt active before it hits the rnaged/melee grp after each bounce we seemed to be doing it right. 20 yrds isnt a huge distance if the tank is on the other side of the boss Id say thats about another 10 yrds from ranged which means hes still in range for spare heals and saves from the healers in the ranged grp. What I felt was really killing us or really hard for the healers to handle was managing the dispells while taking dmg from the ball.
The ball shares its dmg between the people it hits
http://www.wowhead.com/spell=104605 the range is 20 yrds apparently so staying loosley stacked should work, the problem is that it increases its dmg every time the ball bounces not just on the P2 for the boss by 5% but the amount of dmg done to the people it hits by 20% as well. Making it harder for the healers to keep everyone topped up for dispelling as the number of bounces gets higher. Thats probably why we were loosing a good few ranged during the first phase, would have been nice to have another druid healer in the range stack to swamp them with AoE heals constantly while a shammy tops them off and dispels.
Notice both the stacking says 20 yrd and the AoE dmg from the void diffusion says 20 yrds ....I wonder if this is a mistake as Vrug obv didnt take dmg all the time from void diffusion when it was hitting melee...... either that or Im just confused and my reasoning is all wrong (its been known to happen
).
