Chaos Horntail post BB?

I'm thinking of hosting a weekly Chaos Horntail squad for my friends after Big Bang, and I'm just wondering if there are any significant changes to the boss. None of us have any experience fighting it pre-BB, so I'd also like some information on what to expect. I did do some research already, and I'm just going to ask what I couldn't find here instead of bumping an old thread.

My understanding of the fight:

Down 2 preheads

Start from left side
Kill Leg
Kill Tail
Kill Wings
kill Righ Head
Kill Mid Head
Kill Left Head
Kill Right Arms
Kill Left Arms

Miiddle head does slightly more than 12k of dmg with threaten, so it will kill ranged.


I'd appreciate any other tips anyone might have.
