You clearly haven't done any savage content before. Also you haven't done the Stormblood normal raids either.
1st every mechanic in FFXIV has a tell, even Savage Raids.
2nd, DBM doesn't exists in FFXIV* it's a WOW thing, also DBM worked by interpreting Boss Tells, so even in WOW every Fight had easy to read tells, but the player base was too lazy so DBM was able to make their app and be successful.
So far you have not given any actual evidence of an issue, and you are trying to sound like there is one when there is not. And yes, honestly this post really reminds me of That one guy who would often post Troll posts, not to say you are him, and not to say your intent is to troll, but you do seem to behaving in a manner that is indicative of trollish posting.
* DBM tried to design an app for FFXIV at one point, but due to SE stance on addons, and because getting it to work in a game like FFXIV without add support is hard AF, they basically abandoned the effort. There are Apps out their that track game mechanics for FFXIV but they are slow to update, and are frowned upon by the community for the most part, High End raiders may use Trackers for DPS and parsing data, and they may use apps to adjust the UI, and even make the game more pretty, but generally Discord Call Outs and learning the fights is the preferred method of dealing with mechanics.
What is funny about this, if someone looked at my posting main, they wouldn't see my other main. You wouldn't be able to tell I have 1 healer, 1 tank, Ninja, All Ranged DPS (Physical and Magical) at 90. When you see my posting main, you will realize I haven't logged into her since the expansion dropped, moistly because of queue times, but also because I am focused on getting my other main completed first.
It's ok, my main has 7 level 80 jobs and 2 lvl90 jobs. It's silly to judge people here by their posting accounts and people are becoming more aware that the lodestone is being used as a kind of tracking device and therefore are using alts so they don't get tracked either by people here, or by stalkers/weirdos.
I have problems there from all the effects, and I know I can turn them off but that means turning off everything. I'm pretty much 100% blind in that fight and rely on hearing instead.
I had a blast doing this fight. I thought it was well done and I'm not a hardcore raider.
