You're actually wrong though. Pre-7.1 it had 15 oGCD for opener and 2 minute burst, now it has 13 after you subtract the 2 nastrond. It's the same amount oGCD as endwalker, only more frequently and during the opener, while also having more button diversity.

There are limits to how disingenuous people should be when pushing their own weird narratives.
Reading your pastebin is weird too, you say level 70 has 5 oGCD when it actually has 8? What is your logic? 1) Lance Charge, 2) Battle Litany, 3) Geirskogul, 4) Nastrond, 5) High Jump, 6) Mirage Dive, 7) Dragonfire Dive, 8) Life Surge.
Just weird all around.
