Which job are you most looking forward to...

Is it really though?

Yes it is.

It's burst window rotation isn't simply CD > Big Skill x5

It's a 3 step GCD combo with an oGCD to weave in. But that only takes 3 out of 5 GCD's for a standard 10s burst window. So then you have to decide whether you want to do your normal rotation, or take advantage of any buffs and try and apply your 2 DoTs. All the while, having up to 5 other oGCD actions you want to weave in (2x Rough Divide, Blasting Zone, 2x Burst Strike (Fuelled by Bloodfest)) - All within that 10s burst window.

To say nothing about how SkS will be a great stat for GNB due to their burst combo being affected by it, which will then also desync it from rDPS CD's (Since it's base CD is 30s you'll be reducing it from that so it won't easily line up with the 60/90/120/180s rDPS CD's) as well as requiring a Cartridge to initiate (Bearing in mind, if Bloodfest is available, you'd want to use that for 2x Burst Strikes during the window, rather than to initiate the combo and only have 1 Burst Strike).

This is all a lot different than "Hurr Durr Inner Release/Delirium/Requiestcat > 5x Fell Cleave/Bloodspiller/Holy Spirit(Confiteur)" every 90/90/60s that maybe you weave in Upheaval + Onslaught/Flood of Darkness + Plunge/Intervene + Spirits Within during.

That's true, I'm just not sure if it's enough. I do hope you're right though.
