I'm actually one that believes the dangers of 1.0 are a great loss to the open world, which is now inhabited entirely by forgettable trash mobs, at least in 1.0 the Garlean fortress felt like somewhere you did NOT want to be at alone, It felt like the Garlean army was a real threat to us.
Now? now I could solo their entire fort in a matter of moments on any level 50 job, its pathetic what lengths they went too so people didn't feel like the open world was actually a threatening land and worth paying attention it. I'm not saying dying every 10 feet is fun, but the fact I can walk in and decimate single handedly a heavily guarded Garlean fortress... is just laughable, am I suppose to be afraid of our "Main enemy" if the entirety of their armor can be done in by a lone SMN and a few DoTs? What about all the "immersion" people clamor about? How immersive is it that our greatest foe, the looming threat the entire storyline, can be trampled by the dumbest of adventurers all by themselves.
There's a lot of experience lost when everything you face is "pointless trash" in an MMO... Every open world mob is just pointless trash. People just want instant convenience, they want to just run from point A to point B like their mini map and quest markers tell them, ignoring everything in their path and blazing through it as fast as possible to unlock the next instanced dungeon full of trash mobs and trash loot that gives you points. People hate that anything challenging can exist in an MMO, especially if it means they actually have to watch there they walk instead of hitting forward and tabbing out to netflix. But....
I am of the belief that the gravity/weight effect is nothing but a nuisance. Its SE trying to have their cake and eat it too with the Baby's-First-MMO open world, if you want people to deal with monsters, make them worth dealing with or make them not trash tier so that players actually care where they walk and how they traverse the landscape, make them interested in knowing the paths to take or wanting to defeat the enemies (gil, bringing back useful drops in an open world?)... If you don't want them to be fought, then don't bother us with mechanics like mount weight when all it will due is infuriate us enough to demount and 3-shot the annoyance, then remount... This doesn't make the world feel more dangerous, it doesn't make the enemies feel like a threat or feel more alive and useful, it just makes us angry that we're know weighed down for 20 seconds because some insect buzzed to close to our ears, and now we must squash it.
I'm soap boxing here, let me get to the point., So, I'm all for an open world that feels threatening, as it should, because Eorzea is a dangerous place these days, but I'm not for trivial half-hearted attempts at feigning "peril" such as the weight effect. The Weight effect is a meaningless hassle that does nothing to enrich the experience of the open world. If you want people to care enough about your open world, give them a reason too... pestering them with an action that forces them to slow to a crawl or fight an enemy thats no more a threat to you than a level 1 beetle... probably not the best solution.
