I know it's been discussed a lot on this thread, and people tend to lean towards Seraphim heavily, but do you people have significantly different experiences when tanking Mythic Brackenspore ?
We had him tonight on our first night on him at 10% in 25 pulls, and the two times where we got him at 10% I was in a different spec, still without knowing if I should spec Holy Shield or Seraphim. Damage seems way more steady and easy to heal/predict when playing Holy Shield, and although maybe resulting in a higher DTPS, my life is much less spiky and my healers tell me it's way easier to heal (mostly due to the absence of burst-damage during Spores+Boss debuff+Breath).
I tend to agree with them than my life is more stable, although I definitely feel like being naked way more often (since I've traded a spell for a passive and switched HA for DP), and not being able to do anything during Breath but 'pray' for a DP proc.
Here are the logs from tonight (in French because my raidleader is an ass and logs everything in French grr...) : https://www.warcraftlogs.com/reports...ce=41&fight=22
Pulls with Holy shield are #19 to #23.
