So we finally killed H Ashvane last night after about 60 wipes spread out over 6 weeks. Orgozoa went down 20 min later after effectively 2 pulls. After the first 10 pulls or so I knew this fight was going to be a fight against Blizzard's awful tuning and not just the boss itself.
So Ashvane's mechanics don't change with raid size. You always get 3 corals spawning, 3 bubbles on people, and 3 pairs of lasers. This HEAVILY penalizes small raid sizes, especially the laser. During the only time you can actually do damage to the boss, with 2 tanks, 3 heals, and 5-7 dps that we were running for most of the pulls, you always have half or more of your dps unable to pew pew for long stretches of time while they are running lasers out to kill corals.
Most of our dps are fairly good, we have 1-2 who don't really pull their weight but when you have 2 in the 30 percentiles and 5 in the 70 or better it tends to balance out. But not this boss. It was painfully obvious when our best cleaver would be in a bubble, or when all our melee were targeted with lasers.
The last 2 nights on her I just said fuck it and pugged up to 15. 1st pull get her to 5%, a best, and say something along the lines of "alright that was close let's clean that up and not have 2 people dead going into burn phase and we'll have her" top 2 pugs leave. /headdesk Several pulls later it was quitting time. Next night, a fresh run, I pug up to 17 assuming some will leave before Ashvane. Our healers are gripping at me 3 healing 17. I end up kicking a fire mage pulling 7 percentiles and we pull Ashvane with 16, 2/3/11. 1 shot her.
It's fights like these that make it hard to keep up a happy face while raid leading. It doesn't matter if the strategy is good or my players are (mostly) good, blizz screws up some balancing and it's just a big "pull 100 percents or get fucked" to small raid groups. I'm anticipating us gwtting AotC here in a few weeks but damn that boss felt unnecessarily difficult.
