Nope, we downed him so no hate here.
Never play leapfrog with a unicorn.
With that said there really isnt must trick to this fight, sure we are disadvantaged, but one advice I can give is no matter which direction you are preemptively running, make sure you never run out of range of the boss.
"Old" being the correct word. That's no longer the case.
Can we stop using "You were OP in Sunwell/ Season 8/ Molten Core/ Yesterday" as reasoning or a counter-argument?

It helps to be a bit further from the boss, just make sure not to get caught behind 5 or 6 fire plumes when it is time to run in. Keep an eye on the boss' energy bar and move just before he jumps - if it does happen to jump to you you can dodge it and spam DP.
Like some other people said, if you place yourself at the right distance from the boss and move when he gets full energy, you can avoid the leaps 100% of the time.
