Hi guys. Sorry the Ony run didn't go better. Phase 1 and 2 seem down pat, it's 3 that we need to tackle now.
My observations from Phase 3
Taunt and similar abilities do nothing; the only way to get aggro is to establish it the old fashioned way, either by damage or abilities that produce threat (sunder, revenge, etc.)
When preparing her fear, the ground will shake for 2-3 seconds.
When her fear is active, she tends to switch targets whoever is NOT feared... IF her main target is feared. If her main target is not feared (he resisted it, broke it, etc), she remains on him.
When her fear expires AND if she switched targets to someone who was not feared, she appears to then snap back to whomever was on top of her aggro list (hopefully a tank).
To break the initial Phase 3 Starter Fear, I use a trinket that gives me 30 seconds of fear immunity. This is usually long enough to also be immune to her second fear in Phase 3.
To break the other fears in Phase 3, I can only use Berzerker Rage, which requires a switch to Berzerker Stance, a pop of the Zerker Rage, and then a quick switch back to Def stance. This isn't difficult, but the timing is. She's batting me around all over the place, so I cannot always see the ground start to shake before her fear goes off. ALSO: Her fear intervals are not predictable. Zerker rage lasts 10 seconds, and then has a cooldown of 30 seconds. This is enough to be immune to one fear or break one fear, but Onyxia can easily follow up with another fear 5, 10, or 15 seconds later before the ability is ready again.
Tremor totems... I couldn't tell if they were helping. They did seem to bring me out of the fear early on occasion.
I think we have our Phase 1, 2, and transition from 2 to 3 down... the tank/tanks can get aggro. It's then a matter of reducing the times the tank is affected by fear, or breaking fear. :/
Maybe I should stick to the Core.
