Anatman is a tool that was originally made to preserve GL, and now it's been hamfistedly been turned into preserving the twin snakes buff, and all it has going on for it is a neat pose I guess. It still falls into the trap of "button designed to preserve a buff" and leaves the door open again for SE to keep inserting stupid skills "to preserve a buff", when frankly that is the absolute last thing the job needs on its bars and is the same trap the job fell into with GL. Rather than buttons to preserve a buff players will naturally refresh in combat (and can quickly re-apply themselves through their normal rotation or during PB), I'd much rather see a return of some OGCDs we regularly weave in and also wish to time within our burst phases. Maybe this can be reliant on Chakra, maybe they're just normal cooldowns, maybe they unlock during specific stances, any of those would be better than the current set up for me. I'm certain better players could fart and come up with something better than even that garbage I typed out.
The Blitz system, as it has been implemented, effectively cuts off the return of OGCDs unless they make new ones whole cloth. That is likely not going to happen mid-expansion. Ultimately, I feel the cost of just throwing in some new fancy animations for a system that still doesn't feel complete or even good to use was far too high, but the job is stuck with it as is for at least two years. I have no faith that SE can make it better without ripping it all apart. Again.
