The issue, I find, is that a lot of attention is paid to showing off the prowess of the protagonists yet not enough is done to show off the power of the antagonists. This was very evident throughout much of Stormblood. Magnai was shown to cut down a small airship with minimal effort yet realistically his people have little experience when it comes to fighting Garlemald's forces. Hien then later does the same thing. Estinien is also fired upon by countless soldiers yet they all miss and that serves to allow Estinien to swoop in, destroy a large cannon and then escape completely unscathed. I also believe that the soldiers in question were wearing the armour donned by Garlean Purebloods, rather than the armour used by conscripts. There's a spot to accentuate the presence of a third eye, after all.
Now consider for a moment what the third eye's purpose is:
The third eye is believed to considerably improve the race’s capacity for spatial recognition, giving them an advantage over other races when it comes to navigating aircraft or firing weapons.
The losses in Stormblood were of minimal consequence as well.All three appear to have been killed off to artificially elevate Lyse into a leadership position. Gosetsu 'died' though came back not long afterwards. Zenos playing his 'games' is largely irrelevant to the actions of the rest of his troops as they themselves were fighting desperately for their lives - and realistically part of that drive would be to overcome the threats stacked against them so they can see their friends and loved ones again. It never sits well with me as a military man when a story reduces enemy combatants to generic fodder to be cut through like butter even when they are supposed to be a fearsome, complicated foe.The only 'major' deaths recently have been Papalymo, Meffrid and Conrad.
As much as I hate to say it, for all the flaws WoW's storytelling may have as a setting it is not afraid to show off the strengths of its antagonists and have them severely injure or even kill the occasional major protagonist. In FFXIV, however, the stakes often do not feel as high as they should. Zenos openly denounced Garlemald yet the Warrior of Light and other protagonists act like he did not. It feels very contrived.
Now, to highlight something of note in a recent game that I played, Xenoblades Chronicles 2, I'll be vague to avoid spoilers, though tag it just to be safe:
There is a prominent antagonistic faction in the game. They are repeatedly shown to care deeply for one another, all working towards a similar goal. They are also allowed to be successful at various points in the game and genuinely feel like a meaningful threat as a result.
I want to see more of that in FFXIV. As it stands, Garlemald does not appear to be launching a counterattack. I'm fine with that, but it will be very silly if it does later launch one as it will have given both Gyr Abania and Yanxia time to recover and receive support...which will inevitably lead to them overcoming whatever is thrown at them fairly easily judging by the current and past trends.
